Subject [jira] [Commented] (HBASE-7777) HBCK check for lingering split parents should check for child regions

    [ https://issues.apache.org/jira/browse/HBASE-7777?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13574228#comment-13574228

Ted Yu commented on HBASE-7777:
-------------------------------

With the patch, I got:
{code}
  testQuarantineCorruptHFile(org.apache.hadoop.hbase.util.TestHBaseFsck): org.apache.hadoop.hbase.TableNotEnabledException:
testQuarantineCorruptHFile
  testSplitDaughtersNotInMeta(org.apache.hadoop.hbase.util.TestHBaseFsck): Split daughter
region testSplitdaughtersNotInMeta,B,1360297140329.45e7110974671eab56e96c25700db737. cannot
be found in META.
{code}
The tests pass without patch.

> HBCK checks for split parent regions being in meta and hdfs, and reports this as a transient
error. 
> However, split parents, by design, linger around for some time, until its children stops
referring to it. 
> Instead we should check whether the children are there, and do not report anything if
it is so.
