Elliott Clark commented on HBASE-13331:
---------------------------------------
We have a table that is getting tons of edits at all times. So it's splitting
at anytime. HDFS got restarted by accident and so it started throwing errors
for a short amount of time. After that we got a flurry of warns:
{code}
WARN org.apache.hadoop.hbase.master.CatalogJanitor: Daughter region does not
exist: 6fd202b8fbf93ef76efd6d4e9c881a84, parent is:
adb856dff0d045f845b603724f590dea
WARN org.apache.hadoop.hbase.master.CatalogJanitor: Daughter region does not
exist: abb05df75dcf5fefce336f552dab6319, parent is:

WARN org.apache.hadoop.hbase.master.CatalogJanitor: Daughter region does not

{code}
Then opening all of the daughter regions failed to open saying they have
missing referenced files.
