    Description

      In HDFS-12359, a fix for the KMS ACLs required for re-encryption was done. As part of the fix, the following code is used to make sure the local provider cache in the NN is drained.

      if (dir.getProvider() instanceof CryptoExtension) {
        ((CryptoExtension) dir.getProvider()).drain(keyName);
      }
      

      This doesn't work, because the provider is KeyProviderCryptoExtension instead of CryptoExtension - the latter is composite of the former.

      Unfortunately unit test didn't catch this, because it conveniently rolled the from the NN's provider.
