Hive-1.2.1集成HBase-1.3.1不兼容问题

在Hive继承HBase中，二者的通信包就是hive-hbase-handler.jar，极其重要。如果我们用$HIVE_HOME/lib目录下的hive-hbase-handler-x.y.z.jar，那么一般都不会集成成功，反而报错如：

这说明Hive和HBase的版本不兼容。因此，我们必须根据自己安装的Hive和HBase的版本自己重新编译hive-hbase-handler.jar,即依赖引用自己版本的hive和hase的jar包,重新打包hive-hbase-handler.jar

1.重新编译hive-hbase-handler.jar

(1)下载源码

apache-hive-1.2.1-src.tar.gz并解压

(2)导入eclipse

首先，需要在Eclipse中新建一个Java项目，项目名可以随便起，如hivehbase。

然后，我们在src目录下导入hive-handler源码。

在Hive源码中找到hive-handler源码，切记现在hive-handler目录下的java目录，而不是把hive-handler导入。

接着，选择org目录即可。

(3)引入jar包

将$HIVE_HOME/lib 和 $HBASE_HOME/lib下的所有jar包,加到项目的lib下,并buildpath

注意:$HIVE_HOME/lib 和 $HBASE_HOME/lib目录和该项目lib下的zookepper-xxx.jar要替换成现在用的版本

(4)导出jar包,替换掉$HIVE_HOME/lib下的

注意:导出的jar包名字要是hive-hbase-handler.jar

2.注意事项:

1.将$HIVE_HOME/lib和$HBASE_HOME/lib下的zookeeper-xxx.jar替换成现在所用的zookeeper-xxx.jar

2.$HIVE_HOME/lib目录下,用自己编译的hive-hbase-handler.jar替换调之前的那个,切记将之前的那个删掉,不用留在同一目录下,否则会报错ERROR exec.DDLTask: java.lang.NoSuchMethodError: org.apache.hadoop.hbase.HTableDescriptor.addFamily

3.执行hive语句时,要直接在控制台查看当前debug运行日志命令,方便定位错误

 bin/hive -hiveconf hive.root.logger=DEBUG,console 

4.hive执行需要依赖hbase的一些jar包

(方法1) 手动copy缺失的jar包

         拷贝./hbase/lib/目录下的jar包,到$HIVE_HOME/lib/目录

         包括hbase*.jar,metrics*.jar,htrace*.jar

cp $HBASE_HOME/lib/hbase*.jar $HIVE_HOME/lib
cp $HBASE_HOME/lib/metrics*.jar $HIVE_HOME/lib
cp $HBASE_HOME/lib/htrace*.jar $HIVE_HOME/lib

(方法2)设置classpath环境变量(export生命周期仅在一个bash窗口)

export HBASE_HOME=/opt/module/hbase-1.3.1
export HADOOP_HOME=/opt/module/hadoop-2.7.7
export HADOOP_CLASSPATH=`${HBASE_HOME}/bin/hbase mapredcp`
export HIVE_HOME=/opt/module/hive

 

3.重启hive进行验证:

bin/hive -hiveconf hive.root.logger=DEBUG,console

hive运行下面hql后会看到hbase和hive中都建好了表:

CREATE TABLE hive_hbase_emp_table(
empno int,
ename string,
job string,
mgr int,
hiredate string,
sal double,
comm double,
deptno int)
STORED BY 'org.apache.hadoop.hive.hbase.HBaseStorageHandler'
WITH SERDEPROPERTIES ("hbase.columns.mapping" = ":key,info:ename,info:job,info:mgr,info:hiredate,info:sal,info:comm,info:deptno")
TBLPROPERTIES ("hbase.table.name" = "hbase_emp_table");
