[jira] [Commented] (MESOS-3746) Consider introducing a mechanism to provide feedback on offer operations

    [ https://issues.apache.org/jira/browse/MESOS-3746?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14959723#comment-14959723 ] 

Adam B commented on MESOS-3746:
-------------------------------

Some operations (e.g. reservations) can be monitored by checking the master's state json, but this is not fine-grained enough to be reliable.

> Currently, the master does not provide a direct feedback to the framework when an operation is dropped: https://github.com/apache/mesos/blob/master/src/master/master.cpp#L1713-L1715
> A "subsequent offer" is used as the mechanism to determine whether an operation succeeded or not, which is not sufficient if a framework mistakenly sends invalid operations. There should be an immediate feedback as to whether the request was "accepted".
