Hanisha Koneru commented on HADOOP-10571:
-----------------------------------------
Thanks for working on this [~boky01].
In the files modified in the patch, there are a lot of other log messages which
also need to be fixed to avoid string concatenation. For example, lines {{142,
175, 178, 230, 235}} in {{FailoverController}}. It would be good to fix all the
log messages in a file at once.
Covering all the files at once would become huge. We can break this down into
sub-tasks of HDFS-12829.

> When logging an exception, we often convert the exception to string or call
> {{.getMessage}}. Instead we can use the log method overloads which take
> {{Throwable}} as a parameter.
