Sergey Shelukhin commented on HIVE-12528: ----------------------------------------- What do you mean by correct visibility? The approach is the same - the sessions are taken from queue, the sessions are put back into queue. The only logic change is that it's done in parallel; all the threads are joined at the end in the same place. As long as there are no threading issues between different SessionState/TezClient objects, it should be ok. > don't start HS2 Tez sessions in a single thread > ----------------------------------------------- > > Key: HIVE-12528 > URL: https://issues.apache.org/jira/browse/HIVE-12528 > Project: Hive > Issue Type: Bug > Reporter: Sergey Shelukhin > Assignee: Sergey Shelukhin > Attachments: HIVE-12528.patch > > > Starting sessions in parallel would improve the startup time. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
