I am trying to bringup mini cluster and it keeps failing even though I have
right permissions on the directory:

The below file exists and there seems to be a symlink to a path that
doesn't fully exist. Could someone help me point on the right direction?

Hi,

Are you using windows?

If yes and possible then you can try out Ubuntu, its almost like
windows.Most of the people use ubuntu for hadoop.
If its for design environment on windows then you can try Virtual box ( or
WM ware) with ubuntu. I am using hadoop in ubuntu, so did not faced this
problem.

Regards,
Saravanan Nagarajan
