In SplitTransaction, there is a time lap between the marking the > parent offline, and adding of daughters to the META table. This can result in > clients using MetaScanner, of HTable.getStartEndKeys (used by the > TableInputFormat) missing regions which are made just offline, but the > daughters are not added yet. > This is also related to HBASE-4335. -- This message is automatically generated by JIRA.
