-------------------------------------
[~elgoiri] As we were discussing in HDFS-14210 regarding the invocation.
I have extended a Unit Test to demonstrate the problem. Have put up the cases
of file create file, folder and direct on mount operation for the different
Orders. This seems to solve the problem which I was hitting. Pls give a check!!!
[~shubham.dewan] If you too have any extra case for verification which I might
have missed Pls let me know. I will check that too. :)
