[SPARK-25818][CORE] WorkDirCleanup should only remove the directory at the
beginning of tâ¦
## What changes were proposed in this pull request?
The cleanup mechanism will clear all the eligible directories under
SPARK_WORK_DIR. If the other configured paths are the same as the
SPARK_WORK_DIR configuration, this will cause the file directories of other
configuration items to be deleted by mistake. For example, the SPARK_LOCAL_DIRS
and SPARK_WORK_DIR settings are the same.
We should add an another condition which start with 'app-' when removing
the app-* directories in SPARK_WORK_DIR
## How was this patch tested?
