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

Hi Uma, some tests in HDFS failed after this; see {{HDFS-1786}}.  Could you fix them as well?

> When we perform copyToLocal operations from commandLine and if src Path is invalid 
> srcFS.globStatus(srcpath) will return null. So, when we find the length of resulted value,
it will *throw NullPointerException*.
>  Since we are handling generic exception , it will display null as the message.
