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

v2: -1

Generally it is a good idea to drop isTraceEnabled() and isDebugEnabled() but 
since you pass a costly method call (logPeerId()) as a parameter for the logger 
it will be evaluated every time even if the log level is WARN. For these DEBUG 
and TRACE level messages it would be better to keep the if statements.

> ReplicationSource and HBaseInterClusterReplicationEndpoint log messages 
> should include a target Peer identifier

> _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.
