Subject [jira] [Commented] (FLINK-7073) Create RESTful JobManager endpoint
Date Tue, 04 Jul 2017 14:46:00 GMT

    [ https://issues.apache.org/jira/browse/FLINK-7073?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16073766#comment-16073766
] 

Chesnay Schepler commented on FLINK-7073:
-----------------------------------------

Do we want the endpoint to work directly on the Executiongraph or request these actions from
the JobManager via RPC messages?

Note that neither option is currently supported as the {{JobMasterGateway}} does not support
canceling/stopping a job, nor taking a savepoint nor exposes the ExecutionGraph in any way.

> In order to communicate from the {{client}} with a running {{JobManager}} we have to
provide a RESTful endpoint for job specific operations. These operations are:
> * Cancel job (PUT): Cancel the given job
> * Stop job (PUT): Stops the given job
> * Take savepoint (POST): Take savepoint for given job (How to return the savepoint under
which the savepoint was stored? Maybe always having to specify a path)
> * Poll/Subscribe to notifications
