[jira] [Commented] (MESOS-2258) Enable filtering of task information in master/state.json

["Keith Chambers (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/MESOS-2258?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15962137#comment-15962137 ] 

Keith Chambers commented on MESOS-2258:
---------------------------------------

In the past week I received 2 reports of clusters where state.json became > 50Mb leading to  sluggish to unusable Mesos UI. Workaround is to trigger master failover, which does work, but is not something the operators of these particular systems wanted to do on a regular basis.

Support for filtering state.json and implementing filtering in Mesos UI should resolve this issue.

> The masters state endpoint can grow huge (several MB's) in large installations due to data of all running and completed tasks, while other pieces of information (counters, attached slaves and frameworks) are still useful to be polled frequently.
> We can add query parameters to state.json to filter out task information and/or introduce a /metadata.json endpoint with all but task information.
> Any thoughts?
