@ambari275 These are the steps to follow assuming you are logged in as root # su - hdfs $ klist -kt /etc/security/keytabs/hdfs-headless.keytab Then the output should give you the principal to use $ kinit -kt /etc/security/keytabs/hdfs-headless.keytab

@enirys You could refer to the following doc for Hive tuning: https://docs.cloudera.com/HDPDocuments/HDP2/HDP-2.6.5/bk_hive-performance-tuning/content/ch_connectivity-admission-control.html#guidelines-hiveserver2-heaps If you have other services running on the same HS2 node as well, you might want to reduce Hive heap size or move a service to a different node. Are you expecting too many connections as explained in the above doc, else you might want to bring down HS2 heap size? If you do not see too many connections, but notice high heap usage, you might want to take a heap dump as @asish mentioned, and see if there is memory leak. Load balancing across HS2 could take place based on how you are accessing Hive. You could use zooKeeper based connection string.

I finaly found the root cause of this issue, it happens when users connect to ambari web ui and the stay connected for a while then the session is killed due to timeout. In my configuration there are no timeout for : user.inactivity.timeout.default, user.inactivity.timeout.role.readonly.default Setting these properties allows ambari to logout users after a period of inactivity. This error may occurs also when we restart the ambari-server, users still connected with a 401 error message i'm closing this thread and opening a new one with more details about the issue https://community.cloudera.com/t5/Support-Questions/Logout-ambari-s-connected-users-on-ambari-server-restart/td-p/321322
