Hi all,

I am facing a issue while using Zeppelin. I am trying to load some data(not
that big data) into Zeppelin and then build some visualization on it. The
problem is that when I try to run the code first time it's working but
after some time the same code doesn't work. It remains in running state on
gui, but no logs are generated in Zeppelin logs. Also all further tasks are
hanging in pending state.
As soon as I restart  Zeppelin it works. So I am guessing it's some memory
issue. I have read that Zeppelin stores the data in memory so it is
possible that it runs out of memory after some time.
How do I debug this issue? How much is the default memory that Zeppelin
takes at start? Also is there any way that I can run Zeppelin with
specified memory so that I can start the process with more memory. Because
it doesn't make sense to restart Zeppelin after every half hour

Thanks,
Rushikesh Raut
