["Anshum Gupta (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/SOLR-5477?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Anshum Gupta updated SOLR-5477:
-------------------------------

    Attachment: SOLR-5477-CoreAdminStatus.patch

First raw patch with a test that starts tracking completed and in-progress tasks at the CoreAdmin level.
It's nowhere close to being complete on this front and have a few TODOs in there.

I have another patch (will upload in a while) for the CollectionAPI that uses zk to track information at collection level.

Once I have both of them, will have them work together.

> Typical collection admin commands are long running and it is very common to have the requests get timed out.  It is more of a problem if the cluster is very large.Add an option to run these commands asynchronously
> add an extra param async=true for all collection commands
> the task is written to ZK and the caller is returned a task id. 
> as separate collection admin command will be added to poll the status of the task
> command=status&id=7657668909
> if id is not passed all running async tasks should be listed
> A separate queue is created to store in-process tasks . After the tasks are completed the queue entry is removed. OverSeerColectionProcessor will perform these tasks in multiple threads
