Subject [jira] [Commented] (HIVE-10632) Make sure TXN_COMPONENTS gets cleaned up if table is dropped before compaction.
Date Sat, 16 Jan 2016 17:56:39 GMT

    [ https://issues.apache.org/jira/browse/HIVE-10632?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15103288#comment-15103288
] 

Eugene Koifman commented on HIVE-10632:
---------------------------------------

presence of values_tmp_table_N is probably not triggering actual compactions because it has
not delta files...
since it's not an Acid table it shouldn't be in TXN_COMPONENTS in the first place.  Need to
investigate this.

> The compaction process will clean up entries in  TXNS, COMPLETED_TXN_COMPONENTS, TXN_COMPONENTS.
 If the table/partition is dropped before compaction is complete there will be data left in
these tables.  Need to investigate if there are other situations where this may happen and
address it.
