Review Comment:
@cloud-fan In fact, if we set the value of
`spark.sql.hive.filesourcePartitionFileCacheSize` about the same as or even
larger than the value of `spark.driver.memory`, it may cause OOM.
Even if OOM doesn't occur, we should still clean these `FileStatus` objects
in the `Cache` when we close a sparkSession, because they are useless.
