Eugene Koifman created HIVE-16360: ------------------------------------- Summary: 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
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)
