Eugene Koifman reassigned HIVE-16360: ------------------------------------- Assignee: Eugene Koifman > Improve "No delta files or original files found to compact in" message > ---------------------------------------------------------------------- > > Key: HIVE-16360 > URL: https://issues.apache.org/jira/browse/HIVE-16360 > Project: Hive > Issue Type: Improvement > Components: Transactions > Affects Versions: 1.2.0 > Reporter: Eugene Koifman > Assignee: Eugene Koifman > > CompactorMR.run() produces > {noformat} > LOG.error("No delta files or original files found to compact in " + > sd.getLocation() + " for compactionId=" + ci.id); > {noformat} > in some cases even where there are plenty of delta directories in the > partition. > The reason is that compactor won't compact anything above the level of an > open transaction. So if there is a very long running txn, it may filter out > all deltas in a partition. This looks very confusing when looking at the > logs. -- This message was sent by Atlassian JIRA (v6.3.15#6346)
