Michael Webster commented on HBASE-7183:
----------------------------------------
Hi,
Here is a patch that checks the queue size against a configurable property,
replication.source.log.queue.warn, each time a new log is enqueued. Per the
above comments, the default threshold for printing the log message is 2.
> print WARN message if hbase.replication.sizeOfLogQueue is too big

> A metric hbase.replication.sizeOfLogQueue may become big when replication is

> It would be useful if HBase prints WARN log which tells
> hbase.replication.sizeOfLogQueue is too big.
