Hello, I encountered the following problem:

    During the job running, if disconnected from the regionserver where the metastore is
located, the job status cannot be synchronized, the job will be stuck and job's status will
display as running. I have reproduced this problem offline.

How to reproduce ?

    1. See which regionserver the table kylin_metadata is in.

    2. Kill the hbase regionserver process.

    3. You can see the following log in kylin.lg:

!image-2019-12-27-19-52-54-184.png!

    4. The job will always be in running state and it has completed.

I am trying to fix it.
