[GitHub] flink issue #5176: [FLINK-8279][blob] fall back to TaskManager temp director...

Github user EronWright commented on the issue:

    @NicoK was this PR a response to an actual issue, and did it resolve it?
    
    Do I understand correctly that this will cause the JM (blob server) to use `taskmanager.tmp.dirs`?   In addition to the TM blob cache, of course.
    
    For the TM on YARN, is there really any effect?   Looking at MAPREDUCE-6472, seems the temp folder is already within the container.   Can you explain the actual effect?  Thanks.
    
    Note that the Mesos implementation doesn't actually configure `taskmanager.tmp.dirs` at this time (though there's some dead code in TM).  A proper treatment of tmp folders on Mesos would involve the use of volumes.
