> 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
