> The private method was moved by HDFS-12574 to HdfsKMSUtil with different
> signature.
> To accommodate the above method movement, it seems we need to call the
> following method of DFSClient :
> {code}
> public KeyProvider getKeyProvider() throws IOException {
> {code}
> Since the new decryptEncryptedDataEncryptionKey method has this signature:
> {code}
> static KeyVersion decryptEncryptedDataEncryptionKey(FileEncryptionInfo
> feInfo, KeyProvider keyProvider) throws IOException {
> {code}
