Description

Only IOException is catched and logged (in warn).

Every Throwable should be logged in error.

Eg: a RuntimeException occurs in the writeBlock() method. The exception will not be logged, but simply ignored. The socket is closed silently and nothing and an non understandable exception will be thrown in the DFSClient sending the block....
