> problem is during test connection hiveserver2 url is used
> dbc:hive2://ctr-e127-1486658464320-1453-01-000004.hwx.site:10001/; and
> servicediscovery mode is zookeeper,
> tried to connect manually to this url , it failed due to same error, but when
> remove zookeeper service discovery parameter then i was able to connect using
> beeline.
> so it seems somewhere this url is being modified.
> This happens in non WE clusters as well. Though the error is somewhat

> As per [~rmani]:
> Issue being this class
> org.apache.hive.org.apache.hadoop.security.GroupMappingServiceProvider from
> hive-jdbc-1.2.1000.2.6.0.0-*-standalone.jar is getting loaded by ranger
> class-loader where as
> org.apache.hadoop.security.JniBasedUnixGroupsMappingWithFallback is loaded by
> Tomcat class-loader.
> One way to fix is to pack hive-jdbc-1.2.1000.2.6.0.0-*-standalone.jar in
> /usr/hdp/2.6.0.0-*/ranger-admin/ews/webapp/WEB-INF/lib so the type issue will
> be resolved.
