Subject [GitHub] spark issue #19048: [SPARK-21834] Incorrect executor request in case of dyna...

Github user vanzin commented on the issue:

    I'm not sure I understand why is this a problem. What is the undesired behavior that happens
because of this? That's not explained either in the PR nor in the bug.
    
    The way I understand the code, yes, there are potentially redundant calls to update the
target number of executors; but then, `ExecutorAllocationManager` makes that call every time
it wakes up (100ms), so it doesn't seem like that causes any problems.
