Hive与HBase集成进行数据分析

我们把hive的安装包上传的节点3来

解压

现在我们还是老规矩通过notopad++来连接我们的虚拟机来配置文件，把下面这两个文件重命名一下

修改这个文件

对hive-env.sh我们修改这里

下面我们在HDFS下创建目录，这个可以在任何一个节点下创建都可以，我这里就在节点2下创建了

给这个目录赋予权限

配置完之后我们启动一下hive

把这段内容删除掉

从这里开始一直到下面

到最后的这里我们都把他删除掉

然后也是从这里开始到下面

到下面也删除掉

最后留下这些内容

修改配置一下

创建表格

我们创建一个文件

把刚刚创建的文件数据加载到test表里面去

可以看到报错了！！！

http://bigdata-pro01.kfk.com:8088/

成功了！

可以看到并没有创建metastore数据库

现在发现配置文件出现了一个小错误

这个文件的名字没有修改

重新运行一下Hive

我们重新创建一个表

在mysql下查看

回到hive界面我们把数据导入到表dept中

把这段复杂过来到hive-site.xml

修改一下配置

然后我们重启hive

在hive-site.xml下加上这么一句

因为我这里用的是cdh版本的所以我就不需要导包了

可以看到报错了！！

FAILED: Execution Error, return code 1 from org.apache.hadoop.hive.ql.exec.DDLTask. org/apache/hadoop/hbase/HBaseConfiguration

怎么解决呢

首先通过用下面的命令，重新启动hive
./hive -hiveconf hive.root.logger=DEBUG,console 进行debug
查看到错误原因

调遣hbase包错误，配置文件不能加载。

将hbase目录下jar包拷贝到hadoop/lib下，（注意了我这里为了保险起见3个节点都做了这一步）

然后修改hive的配置文件，使hbase的lib包生效

重启一下hive,再次建表

成功！！！

将hbase的9个包拷贝到hive/lib目录下

export HBASE_HOME=/opt/modules/hbase-0.98.6-cdh5.3.0

export HIVE_HOME=/opt/modules/hive-0.13.1/lib

ln -s $HBASE_HOME/lib/hbase-server-0.98.6-cdh5.3.0.jar $HIVE_HOME/lib/hbase-server-0.98.6-cdh5.3.0.jar

ln -s $HBASE_HOME/lib/hbase-client-0.98.6-cdh5.3.0.jar $HIVE_HOME/lib/hbase-client-0.98.6-cdh5.3.0.jar

ln -s $HBASE_HOME/lib/hbase-protocol-0.98.6-cdh5.3.0.jar $HIVE_HOME/lib/hbase-protocol-0.98.6-cdh5.3.0.jar

ln -s $HBASE_HOME/lib/hbase-it-0.98.6-cdh5.3.0.jar $HIVE_HOME/lib/hbase-it-0.98.6-cdh5.3.0.jar

ln -s $HBASE_HOME/lib/htrace-core-2.04.jar$HIVE_HOME/lib/htrace-core-2.04.jar

ln -s $HBASE_HOME/lib/hbase-hadoop2-compact-0.98.6-cdh5.3.0.jar $HIVE_HOME/lib/hbase-hadoop2-compact-0.98.6-cdh5.3.0.jar

ln -s $HBASE_HOME/lib/hbase-hadoop-compact-0.98.6-cdh5.3.0.jar $HIVE_HOME/lib/hbase-hadoop-compact-0.98.6-cdh5.3.0.jar

ln -s $HBASE_HOME/lib/high-scale-lib-1.1.1.jar $HIVE_HOME/lib/high-scale-lib-1.1.1.jar

ln -s $HBASE_HOME/lib/hbase-common-0.98.6-cdh5.3.0.jar $HIVE_HOME/lib/hbase-common-0.98.6-cdh5.3.0.jar

我在这里说一下，最好还是用工具手动导过来把，直接用上面的语句会出错的

结果报错了，查看日志
