Alan Gates commented on HIVE-12353: ----------------------------------- With the commit of HIVE-12832 to master and branch-2.0 I think all of the schema changes needed for this are in. > When Compactor fails it calls CompactionTxnHandler.markedCleaned(). it > should not. > ----------------------------------------------------------------------------------- > > Key: HIVE-12353 > URL: https://issues.apache.org/jira/browse/HIVE-12353 > Project: Hive > Issue Type: Bug > Components: Transactions > Affects Versions: 1.0.0 > Reporter: Eugene Koifman > Assignee: Eugene Koifman > Priority: Blocker > Attachments: HIVE-12353.2.patch, HIVE-12353.3.patch, HIVE-12353.patch > > > One of the things that this method does is delete entries from TXN_COMPONENTS > for partition that it was trying to compact. > This causes Aborted transactions in TXNS to become empty according to > CompactionTxnHandler.cleanEmptyAbortedTxns() which means they can now be > deleted. > Once they are deleted, data that belongs to these txns is deemed committed... > We should extend COMPACTION_QUEUE state with 'f' and 's' (failed, success) > states. We should also not delete then entry from markedCleaned() > We'll have separate process that cleans 'f' and 's' records after X minutes > (or after > N records for a given partition exist). > This allows SHOW COMPACTIONS to show some history info and how many times > compaction failed on a given partition (subject to retention interval) so > that we don't have to call markCleaned() on Compactor failures at the same > time preventing Compactor to constantly getting stuck on the same bad > partition/table. > Ideally we'd want to include END_TIME field. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
