Kihwal Lee updated HDFS-6020:
-----------------------------
Attachment: HDFS-6020.patch
The patch fixes 4 findbugs warnings.
- Three were for ignoring return value of File.delete(). Moved them into a
conditional statement and added logging.
- Fourth was for not closing a FileWriter instance in some cases. This was
originally ignored since it is non-critical and during shutdown. A finally
block has been added to close it at all times.
The fifth warning is not something introduced by recent changes. There already
is an entry in the exception list for this. So I am not fixing this.
