> Currently, there are several improvements we can do for job scheduler:
> * For {{DistributedScheduler}}, it does not check {{isReady()}} for
> checkpoint jobs
> * Since the state lots of executables fetched from HBase are not READY, it's
> better to fetch their output first, which can reduce lots of get requests to
> hbase
> * {{FetcherRunnerWithPriority}} is not enabled in {{DistributedScheduler}},
> which needs to change the lockPath from *{color:#f79232}segmentId{color}* to
> *{color:#f79232}jobId{color}*
