Eugene Koifman created HIVE-12353: ------------------------------------- Summary: 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
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 delete. 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. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
