Ranger测试hive连接错误提示：
org.apache.ranger.plugin.client.HadoopException: Unable to connect to Hive Thrift Server instance.. 
Unable to connect to Hive Thrift Server instance.. 
Could not open client transport for any of the Server URI's in ZooKeeper: Could not establish connection to jdbc:hive2://c2bde55:10000/;serviceDiscoveryMode=zooKeeper;zooKeeperNamespace=hiveserver2: Required field 'client_protocol' is unset!

Could not establish connection to jdbc:hive2://c2bde55:10000/;serviceDiscoveryMode=zooKeeper;zooKeeperNamespace=hiveserver2: Required field 'client_protocol' is unset! Struct:TOpenSessionReq(client_protocol:null, configuration:{use:database=default}). 

Required field 'client_protocol' is unset! Struct:TOpenSessionReq(client_protocol:null, configuration:{use:database=default}). 

解决办法：
使用hdp2.6.1出现，原因是hive相关jar包不匹配问题
1）备份目录：
# cd /usr/hdp/2.6.1.0-129/ranger-admin/ews/webapp/WEB-INF/classes/ranger-plugins/
# cp -r hive hive.bak
2）清空，重新拷贝hive jar包和它的依赖包
rm -rf /usr/hdp/2.6.1.0-129/ranger-admin/ews/webapp/WEB-INF/classes/ranger-plugins/hive/*
cp -r /usr/hdp/2.6.1.0-129/hive/lib/hive-common*.jar /usr/hdp/2.6.1.0-129/ranger-admin/ews/webapp/WEB-INF/classes/ranger-plugins/hive
cp -r /usr/hdp/2.6.1.0-129/hive/lib/hive-jdbc*.jar /usr/hdp/2.6.1.0-129/ranger-admin/ews/webapp/WEB-INF/classes/ranger-plugins/hive
cp -r /usr/hdp/2.6.1.0-129/hive/lib/hive-exec*.jar /usr/hdp/2.6.1.0-129/ranger-admin/ews/webapp/WEB-INF/classes/ranger-plugins/hive
cp -r /usr/hdp/2.6.1.0-129/hive/lib/hive-metastore*.jar /usr/hdp/2.6.1.0-129/ranger-admin/ews/webapp/WEB-INF/classes/ranger-plugins/hive
cp -r /usr/hdp/2.6.1.0-129/hive/lib/hive-service*.jar /usr/hdp/2.6.1.0-129/ranger-admin/ews/webapp/WEB-INF/classes/ranger-plugins/hive
cp -r /usr/hdp/2.6.1.0-129/hive/lib/libfb303*.jar /usr/hdp/2.6.1.0-129/ranger-admin/ews/webapp/WEB-INF/classes/ranger-plugins/hive
cp -r /usr/hdp/2.6.1.0-129/hive/lib/libthrift*.jar /usr/hdp/2.6.1.0-129/ranger-admin/ews/webapp/WEB-INF/classes/ranger-plugins/hive
chmod -R a+x /usr/hdp/2.6.1.0-129/ranger-admin/ews/webapp/WEB-INF/classes/ranger-plugins/hive
cp ../hive.bak/ranger-hive-plugin-0.7.0.2.6.1.0-129.jar /usr/hdp/2.6.1.0-129/ranger-admin/ews/webapp/WEB-INF/classes/ranger-plugins/hive/
3) 改变拥有者
chown -R ranger:ranger /usr/hdp/2.6.1.0-129/ranger-admin/ews/webapp/WEB-INF/classes/ranger-plugins/hive
4）重启ranger服务，然后测试连接。

注明：此方法通过Ranger授权无效，不建议使用，因为Ranger插件默认使用的是hive2，所以需Ambari中hive组件开启HiveServer2 Interactive

同时修改Ranger中hive服务的jdbc.url *值为：

jdbc:hive2:/ip:2181/;serviceDiscoveryMode=zooKeeper;zooKeeperNamespace=hiveserver2-hive2
