[jira] [Commented] (HBASE-18463) Replication sink frequently triggers HBASE-18023 warnings

["Dave Latham (JIRA)" <ji...@apache.org>]

Dave Latham commented on HBASE-18463:
-------------------------------------

Are we warning because these types of operations are harmful or dangerous?  It seems like if they are, maybe we should change replication to avoid them, but if they are not, then we shouldn't be warning about them.

> After HBASE-18023 we warn if the number of operations in a multi operation exceeds a threshold. This is meant to catch potential performance problems or abusive clients. However while testing simple replication scenarios we have observed frequent warnings issued as the sink applies received edit batches. 
> I think we want to either introduce a separate threshold for warning about RPC submitted by the replication client or exclude ops submitted by the sinks entirely. Not sure distinguishing the replication client from normal clients is possible yet.
