Tsz Wo (Nicholas), SZE commented on HADOOP-3530:
------------------------------------------------
The new log message is *not redundant*. There could be two different
exceptions thrown, one from the try{...} and the other one from finally{...}.
We would miss the second exception if we don't log inside finally{...}.
> Redundant error logging in FSNamesystem.

> HADOOP-3509 introduced a new error message which is logged if FSNamesystem
> fails to initialize.
> This message turned out to be redundant, because it should and is logged
> further up the stack say in NameNode.main().
> Right now I see the exception logged twice when I run a stand-alone name-node.
