[jira] [Created] (HDFS-7179) DFSClient should instantiate a KeyProvider, not a KeyProviderCryptoExtension

Andrew Wang created HDFS-7179:
---------------------------------

             Summary: DFSClient should instantiate a KeyProvider, not a KeyProviderCryptoExtension
                 Key: HDFS-7179
                 URL: https://issues.apache.org/jira/browse/HDFS-7179
             Project: Hadoop HDFS
          Issue Type: Sub-task
          Components: encryption
    Affects Versions: 2.6.0
            Reporter: Andrew Wang
            Assignee: Andrew Wang
            Priority: Critical


When fetching delegation tokens, we attempt to cast the KeyProvider to a DTExtension. However, right now the KP is already wrapped into a CryptoExtension, so it will never be a DTExtension, so we aren't able to get delegation tokens from the KMS.
