-----------------------------------
Summary: Should start transaction when auto_check_compaction is
enabled
Key: IMPALA-11045
URL: https://issues.apache.org/jira/browse/IMPALA-11045
Project: IMPALA
Issue Type: Bug
Reporter: Yu-Wen Lai
Assignee: Yu-Wen Lai
This is a follow-up of IMPALA-11032. Currently Impala doesn't open transaction
for select queries, so we might still get a FileNotFound error when there is a
compaction happen after compaction checking and the files get cleaned by the
cleaner. To provide strong guarantee for this compaction checking approach, we
need to open a transaction even for select queries so that the cleaner won't
clean the files.
