Joshua Griffith updated FLINK-8137:
-----------------------------------
Description:
When submitting a new {{FlinkPlan}} using the {{StandaloneClusterClient}}, the
JobManager's REST API appears to hang until the job is submitted. The
submission time may be large enough to cause timeouts if the {{getStatistics}}
and {{createInputSplits}} methods of a job's {{RichInputFormat}} s perform
time-intensive tasks like running external queries. This is exacerbated when a
job contains many such input formats, since they appear to be initialized
sequentially. For a particular job with over 100 inputs, it's typical for the
API (and consequently the web UI) to be non-responsive for 45–60 seconds.
Would it make sense for tasks to have a {{Configuring}} state before the
{{Created}} state to provide greater visibility and indicate that the
JobManager is still healthy?
