hive is not allowed to impersonate hive
上述2个错误，刚开始以为hive的jdbc驱动没有，结果看了一下有，并且同样的官网包直接解压在power服务器上没问题，这是在X86，整了半天，最后找到一个网站
http://www-01.ibm.com/support/docview.wss?uid=swg21972388
借鉴才解决。
原因：
cat /etc/hadoop/conf/core-site.xml
<property> <name>hadoop.proxyuser.hive.groups</name> <value>*</value> </property> <property> <name>hadoop.proxyuser.hive.hosts</name> <value>lh-2.novalocal</value> </property>
原来云主机重启将主机名改成加一个后缀.novalocal，比较坑，安装集群的时候也被坑过。我直接把lh-2.novalocal改成*了，在Ambari上改的。
然后，重连
成功！
