建立HBase的软连接：
#!/bin/sh
#HOST是部署HBase的节点
HOST=(node1,node2,node3)
for host in ${HOST[@]}
do
echo $host
ssh $host "ln -s /usr/lib/hbase/hbase-client-1.0.0-cdh5.11. /usr/lib/hive/lib/"
ssh $host "ln -s /usr/lib/hbase/hbase-common-1.0.0-cdh5.11. /usr/lib/hive/lib/"
ssh $host "ln -s /usr/lib/hbase/hbase-hadoop2-compat-1.0.0-cdh5.11. /usr/lib/hive/lib/"
ssh $host "ln -s /usr/lib/hbase/hbase-hadoop-compat-1.0.0-cdh5.11. /usr/lib/hive/lib/"
ssh $host "ln -s /usr/lib/hbase/hbase-protocol-1.0.0-cdh5.11. /usr/lib/hive/lib/"
ssh $host "ln -s /usr/lib/hbase/hbase-server-1.0.0-cdh5.11. /usr/lib/hive/lib/"
ssh $host "ln -s /usr/lib/hbase/lib/htrace-core-3.0. /usr/lib/hive/lib/"
