----------------------------------------

Nevermind ( use "" instead of new String[0] ), I am obviously tired.

> Currently, users do not know which volumes are failed unless he looks into 
> the logs, this way is not convenient for users. I plan to put the failed 
> volumes in the report of HDFS. Then hdfs administers can use command 
> "bin/hadoop dfsadmin -report" to find which volumes are failed.
