Can you check that the DFSClient Spark uses is the same version as on the
server side ?
The client and server (NameNode) negotiate a "crypto protocol version" -
this is a forward-looking feature.
Please note:
bq. Client provided: []
Meaning client didn't provide any supported crypto protocol version.
Cheers
