Java. IO. IOException: Server asks us to fall back to SIMPLE auth, but this client is configured to only allow secure connections.
Visual is spark client only allow security verification connection, but now hbase is SIMPLE auth,
The most strange is,
Spark task submitted, spark monitoring page don't have the task, could also not submitted, is an error (here with client mode), delete hbase jar package, you can run; Plus hbase jar package, even if the code does not have any information about the operation hbase or phoenix, will also be an error in the beginning, the feeling is not submitted, security verification error,
An error screenshot is as follows:
Great god answer, thank you very much
