本篇博客会简单涉及到滚动编辑，融合镜像文件，目录的空间配额等运维操作简介。话不多少，直接上命令便于以后查看。
一.查看hadf的帮助信息
[hdfs@node101.yinzhengjie.org.cn ~]$ hdfs Usage: hdfs [--config confdir] COMMAND where COMMAND is one of: dfs run a filesystem command on the file systems supported in Hadoop. namenode -format format the DFS filesystem secondarynamenode run the DFS secondary namenode namenode run the DFS namenode journalnode run the DFS journalnode zkfc run the ZK Failover Controller daemon datanode run a DFS datanode dfsadmin run a DFS admin client diskbalancer Distributes data evenly among disks on a given node haadmin run a DFS HA admin client fsck run a DFS filesystem checking utility balancer run a cluster balancing utility jmxget get JMX exported values from NameNode or DataNode. mover run a utility to move block replicas across storage types oiv apply the offline fsimage viewer to an fsimage oiv_legacy apply the offline fsimage viewer to an legacy fsimage oev apply the offline edits viewer to an edits file fetchdt fetch a delegation token from the NameNode getconf get config values from configuration groups get the groups which users belong to snapshotDiff diff two snapshots of a directory or diff the current directory contents with a snapshot lsSnapshottableDir list all snapshottable dirs owned by the current user Use -help to see options portmap run a portmap service nfs3 run an NFS version 3 gateway cacheadmin configure the HDFS cache crypto configure HDFS encryption zones storagepolicies list/get/set block storage policies version print the version Most commands print help when invoked w/o parameters.

综上所述，hdfs有多个子选项，作为一枚新手建议从dfs入手，dfs子选项意思是在hdfs文件系统上运行当前系统的命令，而这些命令跟咱们学习的Linux命令长得几乎一样，接下来我们一起来看看如果使用它们吧。
二.hdfs与dfs结合使用的案例
其实hdfs 和dfs 结合使用的话实际上调用的是hadoop fs这个命令。不信你自己看帮助信息如下：
[hdfs@node101.yinzhengjie.org.cn ~]$ hdfs dfs Usage: hadoop fs [generic options] [-appendToFile <localsrc> ... <dst>] [-cat [-ignoreCrc] <src> ...] [-checksum <src> ...] [-chgrp [-R] GROUP PATH...] [-chmod [-R] <MODE[,MODE]... | OCTALMODE> PATH...] [-chown [-R] [OWNER][:[GROUP]] PATH...] [-copyFromLocal [-f] [-p] [-l] <localsrc> ... <dst>] [-copyToLocal [-p] [-ignoreCrc] [-crc] <src> ... <localdst>] [-count [-q] [-h] [-v] [-x] <path> ...] [-cp [-f] [-p | -p[topax]] <src> ... <dst>] [-createSnapshot <snapshotDir> [<snapshotName>]] [-deleteSnapshot <snapshotDir> <snapshotName>] [-df [-h] [<path> ...]] [-du [-s] [-h] [-x] <path> ...] [-expunge] [-find <path> ... <expression> ...] [-get [-p] [-ignoreCrc] [-crc] <src> ... <localdst>] [-getfacl [-R] <path>] [-getfattr [-R] {-n name | -d} [-e en] <path>] [-getmerge [-nl] <src> <localdst>] [-help [cmd ...]] [-ls [-C] [-d] [-h] [-q] [-R] [-t] [-S] [-r] [-u] [<path> ...]] [-mkdir [-p] <path> ...] [-moveFromLocal <localsrc> ... <dst>] [-moveToLocal <src> <localdst>] [-mv <src> ... <dst>] [-put [-f] [-p] [-l] <localsrc> ... <dst>] [-renameSnapshot <snapshotDir> <oldName> <newName>] [-rm [-f] [-r|-R] [-skipTrash] <src> ...] [-rmdir [--ignore-fail-on-non-empty] <dir> ...] [-setfacl [-R] [{-b|-k} {-m|-x <acl_spec>} <path>]|[--set <acl_spec> <path>]] [-setfattr {-n name [-v value] | -x name} <path>] [-setrep [-R] [-w] <rep> <path> ...] [-stat [format] <path> ...] [-tail [-f] <file>] [-test -[defsz] <path>] [-text [-ignoreCrc] <src> ...] [-touchz <path> ...] [-usage [cmd ...]] Generic options supported are -conf <configuration file> specify an application configuration file -D <property=value> use value for given property -fs <local|namenode:port> specify a namenode -jt <local|resourcemanager:port> specify a ResourceManager -files <comma separated list of files> specify comma separated files to be copied to the map reduce cluster -libjars <comma separated list of jars> specify comma separated jar files to include in the classpath. -archives <comma separated list of archives> specify comma separated archives to be unarchived on the compute machines.

1>.查看hdfs子命令的帮助信息
[hdfs@node101.yinzhengjie.org.cn ~]$ hdfs dfs -help ls -ls [-C] [-d] [-h] [-q] [-R] [-t] [-S] [-r] [-u] [<path> ...] : List the contents that match the specified file pattern. If path is not specified, the contents of /user/<currentUser> will be listed. For a directory a list of its direct children is returned (unless -d option is specified). Directory entries are of the form: permissions - userId groupId sizeOfDirectory(in bytes) modificationDate(yyyy-MM-dd HH:mm) directoryName and file entries are of the form: permissions numberOfReplicas userId groupId sizeOfFile(in bytes) modificationDate(yyyy-MM-dd HH:mm) fileName -C Display the paths of files and directories only. -d Directories are listed as plain files. -h Formats the sizes of files in a human-readable fashion rather than a number of bytes. -q Print ? instead of non-printable characters. -R Recursively list the contents of directories. -t Sort files by modification time (most recent first). -S Sort files by size. -r Reverse the order of the sort. -u Use time of last access instead of modification for display and sorting.

三.hdfs与getconf结合使用的案例
1>.获取NameNode的节点名称(可能包含多个)
[yinzhengjie@s101 ~]$ hdfs getconf hdfs getconf is utility for getting configuration information from the config file. hadoop getconf [-namenodes] gets list of namenodes in the cluster. [-secondaryNameNodes] gets list of secondary namenodes in the cluster. [-backupNodes] gets list of backup nodes in the cluster. [-includeFile] gets the include file path that defines the datanodes that can join the cluster. [-excludeFile] gets the exclude file path that defines the datanodes that need to decommissioned. [-nnRpcAddresses] gets the namenode rpc addresses [-confKey [key]] gets a specific key from the configuration [yinzhengjie@s101 ~]$ hdfs getconf -namenodes s101 [yinzhengjie@s101 ~]$
2>.获取hdfs最小块信息（默认大小为1M,即1048576字节，如果想要修改的话必须为512的倍数，因为HDFS底层传输数据是每512字节进行校验）
[yinzhengjie@s101 ~]$ hdfs getconf hdfs getconf is utility for getting configuration information from the config file. hadoop getconf [-namenodes] gets list of namenodes in the cluster. [-secondaryNameNodes] gets list of secondary namenodes in the cluster. [-backupNodes] gets list of backup nodes in the cluster. [-includeFile] gets the include file path that defines the datanodes that can join the cluster. [-excludeFile] gets the exclude file path that defines the datanodes that need to decommissioned. [-nnRpcAddresses] gets the namenode rpc addresses [-confKey [key]] gets a specific key from the configuration [yinzhengjie@s101 ~]$ hdfs getconf -confKey dfs.namenode.fs-limits.min-block-size 1048576 [yinzhengjie@s101 ~]$
3>.查找hdfs的NameNode的RPC地址

六.hdfs与oiv结合我使用案例
1>.查看hdfs oiv的帮助信息
[yinzhengjie@s101 ~]$ hdfs oiv Usage: bin/hdfs oiv [OPTIONS] -i INPUTFILE -o OUTPUTFILE Offline Image Viewer View a Hadoop fsimage INPUTFILE using the specified PROCESSOR, saving the results in OUTPUTFILE. The oiv utility will attempt to parse correctly formed image files and will abort fail with mal-formed image files. The tool works offline and does not require a running cluster in order to process an image file. The following image processors are available: * XML: This processor creates an XML document with all elements of the fsimage enumerated, suitable for further analysis by XML tools. * FileDistribution: This processor analyzes the file size distribution in the image. -maxSize specifies the range [0, maxSize] of file sizes to be analyzed (128GB by default). -step defines the granularity of the distribution. (2MB by default) * Web: Run a viewer to expose read-only WebHDFS API. -addr specifies the address to listen. (localhost:5978 by default) * Delimited (experimental): Generate a text file with all of the elements common to both inodes and inodes-under-construction, separated by a delimiter. The default delimiter is \t, though this may be changed via the -delimiter argument. Required command line arguments: -i,--inputFile <arg> FSImage file to process. Optional command line arguments: -o,--outputFile <arg> Name of output file. If the specified file exists, it will be overwritten. (output to stdout by default) -p,--processor <arg> Select which type of processor to apply against image file. (XML|FileDistribution|Web|Delimited) (Web by default) -delimiter <arg> Delimiting string to use with Delimited processor. -t,--temp <arg> Use temporary dir to cache intermediate result to generate Delimited outputs. If not set, Delimited processor constructs the namespace in memory before outputting text. -h,--help Display usage information and exit [yinzhengjie@s101 ~]$

七.hdfs与oev结合我使用案例
1>.查看hdfs oev的帮助信息
[yinzhengjie@s101 ~]$ hdfs oev Usage: bin/hdfs oev [OPTIONS] -i INPUT_FILE -o OUTPUT_FILE Offline edits viewer Parse a Hadoop edits log file INPUT_FILE and save results in OUTPUT_FILE. Required command line arguments: -i,--inputFile <arg> edits file to process, xml (case insensitive) extension means XML format, any other filename means binary format -o,--outputFile <arg> Name of output file. If the specified file exists, it will be overwritten, format of the file is determined by -p option Optional command line arguments: -p,--processor <arg> Select which type of processor to apply against image file, currently supported processors are: binary (native binary format that Hadoop uses), xml (default, XML format), stats (prints statistics about edits file) -h,--help Display usage information and exit -f,--fix-txids Renumber the transaction IDs in the input, so that there are no gaps or invalid transaction IDs. -r,--recover When reading binary edit logs, use recovery mode. This will give you the chance to skip corrupt parts of the edit log. -v,--verbose More verbose output, prints the input and output filenames, for processors that write to a file, also output to screen. On large image files this will dramatically increase processing time (default is false). Generic options supported are -conf <configuration file> specify an application configuration file -D <property=value> use value for given property -fs <local|namenode:port> specify a namenode -jt <local|resourcemanager:port> specify a ResourceManager -files <comma separated list of files> specify comma separated files to be copied to the map reduce cluster -libjars <comma separated list of jars> specify comma separated jar files to include in the classpath. -archives <comma separated list of archives> specify comma separated archives to be unarchived on the compute machines. The general command line syntax is bin/hadoop command [genericOptions] [commandOptions] [yinzhengjie@s101 ~]$

八.hadoop命令介绍
在上面我们以及提到过，"hadoop fs"其实就等价于“hdfs dfs”,但是hadoop有些命令是hdfs 命令所不支持的，我们举几个例子：
1>.检查压缩库本地安装情况
