Subject [jira] [Updated] (HIVE-12939) add timeout around prewarm and waitTillReady in Tez session pool session start
Date Wed, 27 Jan 2016 00:12:39 GMT

     [ https://issues.apache.org/jira/browse/HIVE-12939?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Sergey Shelukhin updated HIVE-12939:
------------------------------------
    Description: When one of the default queues is fully used, or not sized correctly, the
corresponding pool sessions may not be able to start in a timely manner (or at all), and HS2
startup would hang forever. Need to add a timeout around that (in Hive for now, since Tez
does not have the APIs that we need).  (was: When one of the default queues is fully used,
or not sized correctly, the corresponding pool sessions may not be able to start in a timely
manner (or at all), and HS2 startup would hang forever. Need to add a timeout around that.)
