Arun Suresh created HDFS-7718:
---------------------------------

             Summary: DFSClient objects created by AbstractFileSystem objects created by FileContext
are not closed and results in thread leakage
                 Key: HDFS-7718
                 URL: https://issues.apache.org/jira/browse/HDFS-7718
             Project: Hadoop HDFS
          Issue Type: Bug
            Reporter: Arun Suresh
            Assignee: Arun Suresh


Currently, the {{FileContext}} class used by clients such as (for eg. {{YARNRunner}}) creates
new {{AbstractFilesystem}} object on initialization.. which creates new {{DFSClient}} objects..
which in turn creates KeyProvider objects.. If Encryption is turned on, and https is turned
on, the keyprovider implementation (the {{KMSClientProvider}}) will create a {{ReloadingX509TrustManager}}
per instance... which are never killed and can leak
