             Summary: Spark doesn't clean up Application Directories (local 
dirs) 
                 Key: SPARK-7917
                 URL: https://issues.apache.org/jira/browse/SPARK-7917
             Project: Spark
          Issue Type: Bug
          Components: Spark Core
    Affects Versions: 1.3.0
            Reporter: Zach Fry


Similar to SPARK-4834. 

Spark does clean up the cache and lock files in the local dirs, however, it 
doesn't clean up the actual directories. 

We have to write custom scripts to go back through the local dirs and find 
directories that don't contain any files and clear those out. 

Its a pretty simple repro: 
Run a job that does some shuffling, wait for the shuffle files to get cleaned 
up, go and look on disk at spark.local.dir and notice that the directory(s) are 
still there, but there are no files in them.
