> The {{addDelegationTokens}} method in {{DistributedFileSystem}} calls {{DFSClient#getKeyProvider()}}
which attempts to get a provider from the {{KeyProvderCache}} but since the required key,
*dfs.encryption.key.provider.uri* is not present (due to encryption being dissabled), it throws
an exception.
