Yifan Zhang has uploaded a new patch set (#5). ( http://gerrit.cloudera.org:8080/19471 )
Change subject: IMPALA-11081: Fix incorrect results in partition key scan ...................................................................... IMPALA-11081: Fix incorrect results in partition key scan This patch fixes incorrect results caused by short-circuit partition key scan in the case where a Parquet/ORC file contains multiple blocks. IMPALA-8834 introduced the optimization that generating only one scan range that corresponding to the first block per file, backends only read footers for Parquet/ORC files, which leads to incorrect results if the first block doesn't include a file footer. This bug is fixed by returning a scan range corresponding to the last block for Parquet/ORC files to make sure it contains a file footer. Testing: - Added e2e tests to verify the fix.
