[jira] [Created] (ZEPPELIN-4091) Ipython hang when concurrent auto complete / run
marc hurabielle created ZEPPELIN-4091: - Summary: Ipython hang when concurrent auto complete / run Key: ZEPPELIN-4091 URL: https://issues.apache.org/jira/browse/ZEPPELIN-4091 Project: Zeppelin Issue Type: Sub-task Reporter: marc hurabielle Assignee: marc hurabielle Ipython / ipython server has a problem when concurrent execution and auto complete are execute in same time / parallel. It can make a paragraph hang forever (until restart of the ipython server). Maybe related to [https://github.com/jupyter/jupyter_client/issues/429] 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 -- This message was sent by Atlassian JIRA (v7.6.3#76005)
[jira] [Created] (ZEPPELIN-4090) Ipython CPU / queue improvement
marc hurabielle created ZEPPELIN-4090: - Summary: Ipython CPU / queue improvement Key: ZEPPELIN-4090 URL: https://issues.apache.org/jira/browse/ZEPPELIN-4090 Project: Zeppelin Issue Type: Sub-task Reporter: marc hurabielle Assignee: marc hurabielle Ipython / ipython server has currently a problem of High cpu usage. The loop that read from the pub/sub should not try to read everytimes the pub sub. It Needs to be debounce. those are the action item: * 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)
[jira] [Created] (ZEPPELIN-4089) Execution hang after ipython kernel die
marc hurabielle created ZEPPELIN-4089: - Summary: Execution hang after ipython kernel die Key: ZEPPELIN-4089 URL: https://issues.apache.org/jira/browse/ZEPPELIN-4089 Project: Zeppelin Issue Type: Sub-task Reporter: marc hurabielle Assignee: marc hurabielle When an ipython paragraph is running, and the ipython kernel is dying. (like an out of memory), the interpreter will hang and never complete the execution. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
[jira] [Created] (ZEPPELIN-4078) Ipython improvement
marc hurabielle created ZEPPELIN-4078: - 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)
