flink git commit: [FLINK-7653] Properly implement
Dispatcher#requestClusterOverview
Repository: flink
Updated Branches:
refs/heads/master 742e4a0ff -> 660a45ca1
[FLINK-7653] Properly implement Dispatcher#requestClusterOverview
This commit implements the ClusterOverview generation on the Dispatcher. In
order to do this, the Dispatcher requests the ResourceOverview from the
ResourceManager and the job status from all JobMasters. After receiving all
information, it is compiled into the ClusterOverview.
Note: StatusOverview has been renamed to ClusterOverview
This closes #4793.
