HDP 2.4 - not starting up, stuck at Starting Zeppelin

[#1]

Hi, i've been using the HDP 2.4 sandbox, and for the 2nd time - it is not starting up.

It seems to be stuck at - Starting Zeppelin

The first time, i wanted to move ahead - so re-downloaded the sandbox, and it started up. I get the feeling it happened after i kerberized the environment.

Any ideas on what needs to be done ?

Pls note - I've allocated 8Gb (of total 16 GB) to the sandbox

thanks !

Are you going to use Zeppelin? If not I will request to remove it unless its major blocker for your testing.

Also if you want to debug - can you please check the logs and see cause of zeppelin service stuck from ambari ui.

Please do attached screenshot if possible.
