Lars Hofhansl commented on HBASE-13471:
---------------------------------------
Maybe this can be caused when the client's cache is slightly out of date? The
usual protocol is to have the region server fail and the client should try
again. For batch mutations that appears to be broken than?! That would be
unbelievably bad!
