There are cases where after using Zeppelin for a while, its interpreter page
does not show. Also I was not able to run any paragraphs anymore (nothing
happens when click run button, not even any message). It seems that something
is broken. Now I have to restart my Zeppelin instance when this happened. After
checking the network calls from interpreter page, it is the
/api/interpreter/setting that is not responding. What may cause the issue? Is
there anything I can do to prevent this from happening?
