> When FileOutputCommitter calls abortTask() to create a temp directory, if the user has
no permission to access the directory, or a file with the same name has existed, of course
it will fail, however the system will output the error information into the log file instead
of throwing an exception.As a result, when the temp directory is needed later, since the temp
directory hasn't been created yet, system will throw an exception to tell user that the temp
directory doesn't exist.In my opinion, the exception is not exact and the error infomation
will confuse users.
