Subject [Impala-ASF-CR] IMPALA-5611: KuduPartitionExpr holds onto memory unnecessarily
Date Wed, 05 Jul 2017 17:06:30 GMT
Hello Matthew Jacobs, Tim Armstrong, Dan Hecht,

I'd like you to reexamine a change.  Please visit

to look at the new patch set (#5).

Change subject: IMPALA-5611: KuduPartitionExpr holds onto memory unnecessarily

IMPALA-5611: KuduPartitionExpr holds onto memory unnecessarily

IMPALA-3742 introduced KuduPartitionExpr, which takes a row and passes
it to the Kudu client to determine what partitionit belongs to.

The DataStreamSender never frees the local allocations for the Kudu
partition exprs causing it to hang on to memory longer than it needs to.

This patch also fixes two other related issues:
- DataStreamSender was dropping the Status from AddRow in the Kudu
- Changes the HASH case in DataStreamSender to call FreeLocalAllocations
  on a per-batch basis, instead of a per-row basis.

- Added an e2e test that runs a large insert with a mem limit that
  failed with oom previously.
