Subject [jira] [Commented] (HBASE-14716) Detection of orphaned table znode should cover table in Enabled state
Date Fri, 30 Oct 2015 00:15:27 GMT

    [ https://issues.apache.org/jira/browse/HBASE-14716?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14981629#comment-14981629
] 

Ted Yu commented on HBASE-14716:
--------------------------------

While debugging test failure, found the following in test output:
{code}
2015-10-29 16:29:58,271 WARN  [Time-limited test] util.HBaseFsck(3278): Table hbase:namespace
not found in hbase:meta. Orphaned table ZNode found.
2015-10-29 16:29:58,272 DEBUG [Time-limited test-EventThread] zookeeper.ZooKeeperWatcher(638):
hbase Fsck-0x150b5ef96250014 connected
ERROR: Table hbase:namespace not found in hbase:meta. Orphaned table ZNode found.
{code}
Looks like tablesInfo is not updated with entry for hbase:namespace

> HBASE-12070 introduced fix for orphaned table znode where table doesn't have entry in
hbase:meta
> When Stephen and I investigated rolling upgrade failure,
> {code}
> 2015-10-27 18:21:10,668 WARN  [ProcedureExecutorThread-3] procedure.CreateTableProcedure:
The table smoketest does not exist in meta but has a znode. run hbck to fix inconsistencies.
> {code}
> we found that the orphaned table znode corresponded to table in Enabled state.
> Therefore running hbck didn't report the inconsistency.
> Detection for orphaned table znode should cover this case.
