can you also add in a debug message here, something like below. I found
this very useful when debugging this issue and think it would be useful for
debugging other allocating issues in the future.
logDebug(s"Updating resource requests, target: $targetNumExecutors,
pending: " +
+ s"$numPendingAllocate, running: $numExecutorsRunning,
executorsStarting $numExecutorsPendingStart")
