------------------------------------
To Jitendra's comment:
That was my first approach to solve the problem. Then I hit on a corner case.
The namenode was in safe mode. The call to getDelegationToken failed and page
displayed an error. I fixed this by invoking getDelegationToken () only if the
namenode is out of safe mode.
But then these links won't work any more unless the page is refreshed.
To avoid these inconsistencies, I used the rediect.
