> i opened the executor dynamic allocation feature, however it doesn't work
> sometimes.
> i set the initial executor num 50, after job finished the cores and mem
> resource did not release.
> from the spark web UI, the active job/running task/stage num is 0 , but the
> executors page show cores 1276, active task 7288.
> from the yarn web UI, the thriftserver job's running containers is 639
> without releasing.
> this may be a bug.
