------------------------------------------

             Summary: HDFSBlobStore leaks file system objects
                 Key: STORM-2764
                 URL: https://issues.apache.org/jira/browse/STORM-2764
             Project: Apache Storm
          Issue Type: Bug
          Components: storm-hdfs
    Affects Versions: 1.0.0, 2.0.0
            Reporter: Robert Joseph Evans
            Assignee: Robert Joseph Evans


This impacts all of the releases.  Each time we create a new HDFSBlobStore 
instance we call 

https://github.com/apache/storm/blob/v1.0.0/external/storm-hdfs/src/main/java/org/apache/storm/hdfs/blobstore/HdfsBlobStore.java#L140

loginUserFromKeytab.

This results in a new subject being created each time when ends up causing a 
FileSystem object to leak each time.
