Taking out the extra headroom
> 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
> Attachments: HIVE-16318.01.patch, HIVE-16318.02.patch,
> HIVE-16318.03.patch, HIVE-16318.04.patch, HIVE-16318.patch

> 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.
