[jira] [Updated] (HIVE-10535) LLAP: Cleanup map join cache when a query completes

["Sergey Shelukhin (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/HIVE-10535?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Sergey Shelukhin updated HIVE-10535:
------------------------------------
    Attachment: HIVE-10533.patch

This isolates LLAP caches by query, and on dag completion simply removes the cache for this query entirely. I am assuming by how other maps are treated that the event is pretty much guaranteed so this won't leak; otherwise periodic cleaner is needed (for this and other maps).

[~gopalv] [~sseth] do you guys want to review?
I haven't tested on cluster yet, might add some logging for that
