Tim Armstrong resolved IMPALA-3700.
-----------------------------------
Resolution: Duplicate
This is just one case of IMPALA-3706. I don't think it's worth tracking
separately for now.
> Introduce upper limit to hash table size or HashBuckets for Streaming agg
> -------------------------------------------------------------------------
>
> Key: IMPALA-3700
> URL: https://issues.apache.org/jira/browse/IMPALA-3700
> Project: IMPALA
> Issue Type: New Feature
> Components: Backend
> Affects Versions: Impala 2.7.0
> Reporter: Mostafa Mokhtar
> Priority: Minor
> Labels: memory, supportability
> Attachments: query67.sql.1.out, query67.sql.1.profile.out
>
>
> Several queries consume all the memory limit in Streaming agg leaving very
> little memory left for other operators.
> Attached is the profile for TPC-DS Q67 which fails for the reason mentioned.
> An alternative solution is to extend the operator interface to respond to
> memory pressure by spilling and releasing some memory back to the
> memory/block manager.
