             Summary: LLAP cache: address some issues in 2.2/2.3
                 Key: HIVE-16318
                 URL: https://issues.apache.org/jira/browse/HIVE-16318
             Project: Hive
          Issue Type: Bug
            Reporter: Sergey Shelukhin
            Assignee: Sergey Shelukhin


We've run into HIVE-16233 and HIVE-15665 and given that 2.2 and 2.3 releases are approaching
we are going to add workarounds for them, and then commit the above patches and revert the
workarounds as soon as we can.
Unfortunately this will result in cache wasting some memory on some datasets, but the alternatives,
when they are encountered (usually only on large datasets), are worse.
