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