>
> If we have replication setup between clusters A <-> B, during production
> incidents where HFiles get corrupted (e.g. via hdfs missing blocks) on
> cluster A, we can use CopyTable job to copy the data from B
> In those cases considering the data is being copied from B to A via
> CopyTable, it doesn't make sense to write to WALs on A using
> TableOutputFormat (since the mutations being copied already exist on B).
> We can add a config to customise durability
> ([https://github.com/apache/hbase/blob/master/hbase-client/src/main/java/org/apache/hadoop/hbase/client/Durability.java])
> within TableOutputFormat so that an operator can use it to skip WAL writes
