近期准备上线了一个基于HBase的hive，但是通过spark查询这个hive表的时候出现了如下异常：
19/12/21 15:27:18 ERROR log: error in initSerDe: java.lang.ClassNotFoundException Class org.apache.hadoop.hive.hbase.HBaseSerDe not found

出错的原因是没有找到HBaseSerDe，这个类是在hive-hbase-handler的jar包中，具体目录对应CDH版本的位置在/opt/cloudera/parcels/CDH/jars目录下面
[root@data2 jars]# pwd
/opt/cloudera/parcels/CDH/jars
[root@data2 jars]# ls -l|grep hive-hbase
-rw-r--r-- 1 root root 119117 Jul 19 01:55 hive-hbase-handler-2.1.1-cdh6.3.0.jar
在spark目录下建立一个ln指向这个jar包，问题解决
[root@data3 ~]# cd /opt/cloudera/parcels/CDH/lib/spark/jars
[root@data3 jars]# ln -s /opt/cloudera/parcels/CDH/jars/hive-hbase-handler-2.1.1-cdh6.3.0.jar hive-hbase-handler-2.1.1-cdh6.3.0.jar
