Description

The following questions should be answered for the different deployment modes (application cluster, per-Job cluster, session cluster) and deployment backends (Standalone/Local, Kubernetes, Yarn, Mesos):

• Does the TaskManager metrics page (path: /#/task-manager/<taskmanager-id>/metrics) looks as proposed in FLIP-102 (minor improvements where introduced in )? It helps to have a job running to see whether the metrics in the right column are actually dynamically changing.
• Check whether all 8 newly introduced metrics are exposed through the TaskManager's metric endpoint:
• Does the JobManager metrics page (path: /#/job-manager/metrics) as proposed in FLIP-104?
• Does the Cluster configuration endpoint include /#/job-manager/config include memory-related parameters like jobmanager.memory.heap.size, jobmanager.memory.jvm-metaspace.size, or jobmanager.memory.off-heap.size? Do they match configuration parameters possibly set in the config file?
  Improved unaligned checkpointing times under backpressure
