Hi Snehit,

Seems like Zeppelin can't connect remote interpreter (for example, spark).
Could you restart the interpreter which is bound to notebook and try again?

Hope it helps.

Thanks,

Hi User,

I have been running zeppelin. While everything seems to be fine [Zeppelin build 
was fine, Zeppelin was running, etc], when I am running any query from the 
zeppelin notebook, I am getting the following error:

Could anyone help in solving this issue, I have searched a lot about this in 
google. But, nothing seems to be working.

Any help would be greatly appreciated!!

Thanks in advance,
Snehit
