> In HIVE-13429, we introduce a tool which clear dangling scratch directory. In
> this ticket, we want to invoke the tool automatically on a Hive cluster.
> Options are:
> 1. cron job, which would involve manual cron job setup
> 2. As a metastore thread. However, it is possible we run metastore without
> hdfs in the future (eg, managing s3 files). ClearDanglingScratchDir needs
> support which only exists in hdfs, it won't work if the above scenario happens
> 3. As a HS2 thread. The downside is if no HS2 is running, the tool will not
> run automatically. But we expect HS2 will be a required component down the
> road
> Here I choose approach 3 in the implementation.
