> HDFS-7931 added a check in DFSClient for encryption {{isHDFSEncryptionEnabled()}}, looking
for the property {{"dfs.encryption.key.provider.uri"}.
> This probe returns true even if the property is empty.
> If there is an empty provider.uri property, you get an NPE when a YARN client tries to
set up the tokens to deploy an AM.
