I have solved the similar issue before. You should check on spark UI and probably you will see your single job is taking all the resources. Therefore further job that submitting to the same cluster will just hang on there. When you restart zeppelin then the old job is killed and all the resource it took will be released

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
