Summary: Fix QueryMaintenance calls in Aggregators
Key: IMPALA-7251
URL: https://issues.apache.org/jira/browse/IMPALA-7251
Project: IMPALA
Issue Type: Bug
Affects Versions: Impala 3.1.0
Reporter: Thomas Tauber-Marshall
Assignee: Thomas Tauber-Marshall
A recent change, IMPALA-110 (part 2), refactored PartitionedAggregationNode
into several classes, including GroupingAggregator. During this refactor, code
that makes local allocations while evaluating exprs was moved from the ExecNode
(now AggregationNode/StreamingAggregationNode) into the new type Aggregator,
but code related to cleaning these allocations up (ie QueryMaintenance()) was
not, resulting in some queries using an excessive amount of memory.
