@Sri Bandaru

Below should solve this error after adding in below path.

Ambari -> HDFS -> Config -> Core Site.

hadoop.proxyuser.HTTP.groups = *

hadoop.proxyuser.HTTP.hosts =*

But still I'm facing the issue. Do someother proxy is impersonating it.

@Rahul Pathak

I got the solution,

When debugging pig view issue, found that in WebHCat log that

“/usr/hdp/2.3.2.0-2950/hive/lib/hive-common.jar/zookeeper.jar: cannot open `/usr/hdp/2.3.2.0-2950/hive/lib/hive-common.jar/zookeeper.jar' (No such file or directory) “.

I was getting this from property templeton.libjars where I don’t have /hive/lib/hive-common.jar/zookeeper.jar path. So I have changed path to point appropriate jar file in "/usr/hdp/${hdp.version}/zookeeper/zookeeper.jar,/usr/hdp/${hdp.version}/hive/lib/hive-common.jar" location.
