After a spark program completes, there are 3 temporary directories remain in the temp directory. The directory names are like this: spark-2e389487-40cc-4a82-a5c7-353c0feefbb7
The directories are empty.
And when the Spark program runs on Windows, a snappy DLL file also remains in the temp directory. The file name is like this: snappy-22.214.171.124-6e117df4-97b6-4d69-bf9d-71c4a627940c-snappyjava
They are created every time the Spark program runs. So the number of files and directories keeps growing.
How can let them be deleted?
Spark version is 1.3.1 with Hadoop 2.6.
