> We found this issue when running large scale ingestion tests for HBASE-5754. 
> The problem is that the .META. table updates are not atomic while splitting a 
> region. 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.
