Cloudera Kafka HDFS Sink Connector cannot connect to simple authentication HDFS

[#1]

I've encountered this error log at cloudera HDFS sink connector. (I erased only hostname)

org.apache.kafka.connect.errors.ConnectException: org.apache.kafka.connect.errors.ConnectException: java.io.IOException: DestHost:destPort 
Failed on local exception: java.io.IOException: Server asks us to fall back to SIMPLE auth, but this client is configured to only allow secure connections. 

As this log says, the destination HDFS uses SIMPLE authentication. (hadoop.security.authentication=simple)

Is there any way to connect cloudera HDFS sink connector to HDFS with simple authentication?

I've recovered this error. It was caused by wrong hdfs.uri
