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
