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

Hi Amreshwari,
>From my understanding, the while loop and try catch block takes care that the FileSystem must be initialised properly and then only JobTracker should proceed with other tasks.

Do you see any scenario where the org.apache.hadoop.mapred.JobTracker.getSystemDir() is called even before the fs is set?

Thanks & Regards,
Abhijit

> It should check if fileSystem is null and throw IllegalStateException, as in getFilesystemName method.
