Jason Dere updated HIVE-17482: ------------------------------ Attachment: HIVE-17482.5.patch Added a unit test to TestAcidOnTez, will post update to RB > External LLAP client: acquire locks for tables queried directly by LLAP > ----------------------------------------------------------------------- > > Key: HIVE-17482 > URL: https://issues.apache.org/jira/browse/HIVE-17482 > Project: Hive > Issue Type: Sub-task > Components: llap > Reporter: Jason Dere > Assignee: Jason Dere > Attachments: HIVE-17482.1.patch, HIVE-17482.2.patch, > HIVE-17482.3.patch, HIVE-17482.4.patch, HIVE-17482.5.patch > > > When using the LLAP external client with simple queries (filter/project of > single table), the appropriate locks should be taken on the table being read > like they are for normal Hive queries. This is important in the case of > transactional tables being queried, since the compactor relies on the > presence of table locks to determine whether it can safely delete old > versions of compacted files without affecting currently running queries. > This does not have to happen in the complex query case, since a query is used > (with the appropriate locking mechanisms) to create/populate the temp table > holding the results to the complex query. -- This message was sent by Atlassian JIRA (v6.4.14#64029)
