ramkrishna.s.vasudevan commented on HBASE-15425:
------------------------------------------------

What is the specific reason for the WAL markers to be igonored?  Suppose a 
region open marker is ignored due to exception what happens on Log replay?
How is the flush marker getting reused from the WAL? I have not seen this code 
fully to know the full behaviour.

> Failing to write bulk load event marker in the WAL is ignored

> During LoadIncrementalHFiles process if we fail to write the bulk load event 
> marker in the WAL, it is ignored. So this will lead to data mismatch issue in 
> source and peer cluster in case of bulk loaded data replication scenario.
