Subject Hung LivySpark interpreters
Date Mon, 21 Oct 2019 07:12:46 GMT
Hi,

On my prod instance, Zeppelin becomes unresponsive for LivySql and Livy
Spark interpreters.
I see the below in the thread dumps for Zeppelin and Livy Interpreter
process but not sure why it leads to hung state. All the queries are going
in Pending state and stays as Pending for all the users.

*1. Zeppelin thread dump*


*2.Livy Interpreter thread dump*
