[jira] [Resolved] (SPARK-13115) RandomForest is stuck at computing
same stage over and over
[ https://issues.apache.org/jira/browse/SPARK-13115?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Sean Owen resolved SPARK-13115.
-------------------------------
Resolution: Invalid
Target Version/s: (was: 1.5.2)
Without more info, this didn't necessarily sound like a problem. Anything can be slow without enough resource. You would have to narrow down why you think something is stuck and ideally propose a change.

> URL: https://issues.apache.org/jira/browse/SPARK-13115
> Project: Spark
> Issue Type: Bug
> Components: ML, MLlib, Spark Core
> Affects Versions: 1.5.2
> Reporter: Rahul Tanwani
> Attachments: Stage details.png, Stages.png, Task details.png

>
> While running the RandomForest regression, the algorithm keeps computing the same stage and does not proceed any further. I have observed the same stage being computed for more than 11 hours. Attached are some of the captures from Spark WebUI.
> Also, the spark event logs for this model run could be fetched from Spark Event Logs (https://s3.amazonaws.com/com.tookitaki.public.logs/spark-event-logs). I am running spark-1.5.2 in the standalone local mode. Also, I wanted to know why any stage is marked skipped?
> Let me know if you would need more information.
