Apache Hbase安装及运行

安装hbase1.4，确保在这之前hadoop是正常运行的。设置相应的环境变量，
export HADOOP_HOME=/u01/hadoop
export HBASE_HOME=/u01/hbase
export PATH=$PATH:$HADOOP_HOME/bin:$HBASE_HOME/bin

启动hbase
./start-hbase.sh

确保hadoop, hbase能正常启动，如有问题，可自行搜索文档解决。
[oracle@ol66 bin]$ jps
11685 NodeManager
11157 SecondaryNameNode
10844 NameNode
11405 ResourceManager
13135 HMaster
13455 Jps
10959 DataNode

确保hbase在hadoop上正常运行
[oracle@ol66 u01]$ hdfs dfs -ls /

Version 1.4.0, r10b9b9fae6b557157644fb9a0dc641bb8cb26e39, Fri Dec 8 16:09:13 PST 2017

hbase(main):001:0> list
TABLE
0 row(s) in 0.3800 seconds

=> []
hbase(main):002:0>

可以看到，系统中还没有任何表。

OGG安装及测试

配置OGG for bigdata的环境变量
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$JAVA_HOME/jre/lib/amd64/server

安装ogg for bigdata 12.3版本软件
进入ggsci
ggsci>create subdirs

退回到操作系统命令行，在OGG安装目录下执行如下命令，拷贝hbase示例投递参数后进行修改
cp AdapterExamples/big-data/hbase/* dirprm/
在dirprm目录下，编辑hbase.props文件。
根据安装的hbase的路径，修改gg.classpath中 hbase lib的路径；保存退出。
hbase.props的完整内容如下：

gg.handlerlist=hbase

gg.handler.hbase.type=hbase
gg.handler.hbase.hBaseColumnFamilyName=cf
gg.handler.hbase.keyValueDelimiter=CDATA[=]
gg.handler.hbase.keyValuePairDelimiter=CDATA[,]
gg.handler.hbase.encoding=UTF-8
gg.handler.hbase.pkUpdateHandling=abend
gg.handler.hbase.nullValueRepresentation=CDATA[NULL]
gg.handler.hbase.authType=none
gg.handler.hbase.includeTokens=false

gg.handler.hbase.mode=tx

goldengate.userexit.timestamp=utc
goldengate.userexit.writers=javawriter
javawriter.stats.display=TRUE
javawriter.stats.full=TRUE

gg.log=log4j
gg.log.level=INFO
gg.report.time=30sec

gg.classpath=/u01/hbase/lib/*:/u01/hbase/conf/:

javawriter.bootoptions=-Xmx512m -Xms32m -Djava.class.path=ggjava/ggjava.jar

重新进入GGSCI，使用示例参数和示例队列创建投递进程。
GGSCI>add replicat rhbase, exttrail AdapterExamples/trail/tr
rhbase.prm的内容如下：

REPLICAT rhbase
-- Trail file for this example is located in "AdapterExamples/trail" directory
-- Command to add REPLICAT
-- add replicat rhbase, exttrail AdapterExamples/trail/tr
TARGETDB LIBFILE libggjava.so SET property=dirprm/hbase.props
REPORTCOUNT EVERY 1 MINUTES, RATE
GROUPTRANSOPS 10000
MAP QASOURCE.*, TARGET QASOURCE.*;

测试

可以看到，OGG配置投递到Hbase非常简单，可以根据DB中表的主键字段创建key，如果没有PK字段，则投递时会报错。以下是当前OGG版本支持的Hbase版本
