Peter Somogyi commented on HBASE-22731:
---------------------------------------

Thanks [~wchevreuil]! Looks good, 2 minor comments.

logPeerId() adds a trailing space but most of the times you add an extra space 
before the actual log message:
{code:java}
LOG.info("{} Interrupted while waiting {} to stop", logPeerId(), 
worker.getName());
{code}
except in this case:
{code:java}
LOG.trace("{}{}, sleeping {} times {}", logPeerId(), msg, sleepForRetries, 
sleepMultiplier);
{code}
I noticed that you moved this.metrics.incrSizeOfLogQueue(); into isTraceEnabled 
check. Previously this metric was increased regardless of the log level. Was it 
a bug?

> _ReplicationSource_ and _HBaseInterClusterReplicationEndpoint_ already 
> include a good number of helpful DEBUG and TRACE log messages to help us 
> troubleshooting typical replication problems, such as lags or mysteriously 
> missing edits on target peer. 
> However, for each configured peer, there will be an individual 
> _ReplicationSource_/_HBaseInterClusterReplicationEndpoint_ pair running in 
> parallel, in scenarios where we need to investigate issues within a source to 
> an specific peer, we can't distinguish from which peer specific 
> _ReplicationSource_/_HBaseInterClusterReplicationEndpoint._ For such cases it 
> would be nice to have an identifier for specific peer the given 
> _ReplicationSource_/_HBaseInterClusterReplicationEndpoint_ is related to.
