Ajit Kumar created AMBARI-17776: ----------------------------------- Summary: HiveServer interactive stop should wait for 30 second before sending kill -9 Key: AMBARI-17776 URL: https://issues.apache.org/jira/browse/AMBARI-17776 Project: Ambari Issue Type: Bug Components: ambari-server Affects Versions: 2.4.0 Reporter: Ajit Kumar Assignee: Ajit Kumar Fix For: 2.4.0
Currently when stopping Hive server interactive, the following steps seem to be taken. 1. Send kill to hive server interactive process 2. Wait for 5 seconds and send kill -9 if process in not killed. If HS2 is not shutdown properly - long running sessions (AMs) started by it will not be killed. In case of LLAP - these sessions will typically run for hours. Without the kill - LLAP cannot be restarted, since the old sessions will exist in the LLAP queue, and due to the precise capacity calculations - the queue will not have enough capacity to start new sessions. Ideally it should wait for 30 second before sending kill -9 -- This message was sent by Atlassian JIRA (v6.3.4#6332)
