daughter region issue

[Corbin Hoenes]

Using hbase 0.90.4 and seeing this in the logs:

2011-11-11 13:36:23,130 WARN org.apache.hadoop.hbase.master.CatalogJanitor: 
Daughter regiondir does not exist: 
hdfs://{server}:8020/hbase/{table}/6b1dc05233964d9d57f4ebbc4404f3c4

This looks like this issue: https://issues.apache.org/jira/browse/HBASE-4238, I 
am not sure I understand how serious this is...does it need manual cleanup 
until we can apply the patch?
