Anoop Sam John commented on HBASE-15425:
----------------------------------------
bq.For region replicas, missing a flush file or bulk load files is not a
critical condition (since eventually they will be picked up due to compactions)
Regarding the bulk load markers, that is not for Region replicas.. It is for
replication across cluster. These wal marker cells also will be passed via the
Replication path and the sink cluster will read the cell and do load the file
there also.. So a miss in writing this cell to WAL while bulk load will result
in all these bulk loaded data not getting available for peer cluster. (And no
time later also it can get available)
But ya what ur point of retry and loading the file again ! Need to see any
impact. So these 2 files will have diff seqIds?
> 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.
