Hey @Tsuyoshi Sanda! Looks like this 1001 user is setting manually this hiveconf (including the hive.metastore.client.socket.timeout), if your concern is to impact your hive sessions with a low value for hive.metastore.client.socket.timeout, don't worry about it. Cause that command hive -e "set;"| grep -i hive.metastore.client.socket.timeout its showing that Ambari is able to set the correct value to your hive sessions. And going further to figure out what's happening, I'd login as 1001 and run the pstree on those strange PID's. In the meantime, What it seems to be weird, is root/1001 users are running the same command at the end (hive + show databases), and login as ambari-qa. Try to grep the PID 2767 and if you able share with us, please. Hope this helps! ... View more
