Subject [GitHub] flink issue #3971: [FLINK-6477][web] Waiting the metrics retrieved from the ...

    No it will happen very easily. Some TM does down, bam webUI is frozen for 10 seconds.
    That's too much of an "if" for something that has a workaround; you can refresh the page
after all, or not effectively disable the web-refresh interval.
    
    The update interval is set to 10 seconds by design to keep the additional stress on the
network as well as the JM/TM to a minimum. Especially in larger deployments reducing the interval
could have a noticeable effect; the current policy however is that the metric system should
not incur any noticeable overhead.
