Himanshu Vashishtha commented on HBASE-8229:
--------------------------------------------

Yea, I wonder if we show a replication tab on master UI or somewhere which shows some kind of replication state. Basic errors like table not existing on slave, missing family, or may be exception thrown by the slave at peer level are shown. That should give some basic idea to the user. What others think about this?

> One of our RS/DN machines ran out of diskspace on the partition to which we write the log files.
> It turns out we still had a table in our source cluster with REPLICATION_SCOPE=>1 that did not have a matching table in the remote cluster.
> In then logged a long stack trace every 50ms or so, over a few days that filled up our log partition.
> Since ReplicationSource cannot make any progress in this case anyway, it should probably sleep a bit before retrying (or at least limit the rate at which it spews out these exceptions to the log).
