Sergey Shelukhin updated HIVE-20547: ------------------------------------ Attachment: HIVE-20547.01.patch > HS2: support Tez sessions started by someone else (part 1) > ---------------------------------------------------------- > > Key: HIVE-20547 > URL: https://issues.apache.org/jira/browse/HIVE-20547 > Project: Hive > Issue Type: Bug > Reporter: Sergey Shelukhin > Assignee: Sergey Shelukhin > Priority: Major > Attachments: HIVE-20547.01.patch, HIVE-20547.patch > > > The registry/configs/some code is based on a private patch by [~prasanth_j]. > The patch refactors tez pool session to use composition instead of > implementation inheritance from TezSessionState, to allow for two > implementations of TezSessionState. > For now it's blocked on getClient API in Tez that will be available after > 0.9.3 release; however I commented out that path to check that refactoring > passes tests. > When 0.9.3 becomes available, we can uncomment and commit. > In part 2, we may add some tests, and also consider other changes that are > required for external sessions (e.g. KillQuery, where we cannot assume YARN > is present). > We may also consider a WM change that allows for proportional session > distribution when the number of external sessions and the number of > admin-specified sessions doesn't match, or at least some validation to see > that the external sessions are available when applying a RP. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
