Hello Marcel Kornacker, Tim Armstrong, I'd like you to reexamine a change. Please visit
http://gerrit.cloudera.org:8080/5274 to look at the new patch set (#5). Change subject: IMPALA-4458: Fix resource cleanup of cancelled mt scan nodes. ...................................................................... IMPALA-4458: Fix resource cleanup of cancelled mt scan nodes. The bug was that HdfsScanNodeMt::Close() did not properly clean up all in-flight resources when called through the query cancellation path. The main change is to clean up all resources when passing a NULL batch into HdfsparquetScanner::Close() which also needed similar changes in the scanner context. Testing: Ran test_cancellation.py, test_scanners.py and test_nested_types.py with MT_DOP=3. Added a test query with a limit that was failing before. A regular private hdfs/core test run succeeded.
