Tim Armstrong updated IMPALA-6015:
----------------------------------
Priority: Trivial (was: Minor)
> Simplify ownership of FilterContexts and MemPools in ScannerContext once
> non-MT scan node is removed
> ----------------------------------------------------------------------------------------------------
>
> Key: IMPALA-6015
> URL: https://issues.apache.org/jira/browse/IMPALA-6015
> Project: IMPALA
> Issue Type: Sub-task
> Components: Backend
> Affects Versions: Impala 2.11.0
> Reporter: Tim Armstrong
> Priority: Trivial
>
> The ownership of these objects is a bit complicated because they can be
> either stack-allocated in the scanner thread or owned by a single-threaded
> scan node .
> It should be possible to simplify this once the multithreaded scan node is
> removed.
> See https://gerrit.cloudera.org/#/c/8025/11/be/src/exec/scanner-context.h@337
> for some context.
