Summary: Ipython improvement Key: ZEPPELIN-4078 URL: https://issues.apache.org/jira/browse/ZEPPELIN-4078 Project: Zeppelin Issue Type: Bug Components: python-interpreter Affects Versions: 0.8.1 Environment: tested in linux / macos. Tested the ipython server directly. Reporter: marc hurabielle Ipython / ipython server has currently mutliple problem. * Concurrent execution and auto complete can make a paragraph hang forever (until restart of the ipython server). Maybe related to [https://github.com/jupyter/jupyter_client/issues/429] * Out of memory for ipython will make a paragraph hang instead of throw one error. * High cpu usage. The loop that read from the pub/sub should not try to read everytimes the pub sub. Need to be debounce. Overall most of those bug might be related also to some jupyter_client bug or wrong usage. However, those are the action item: * synchronize auto complete / paragraph execution for now * check the kernel status when we are checking for the thread * sleep time to time when there is no message in pub/sub * Use only one queue instead of 3 ? -- This message was sent by Atlassian JIRA (v7.6.3#76005)
