Anshum Gupta updated SOLR-5477:
-------------------------------
Attachment: SOLR-5477.patch
Considering that the OCP itself might have long running tasks and it's
currently single threaded, we don't want it to be blocked.
I've introduced multi threading in the OCP using a local TPE.

> 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
