Cause Analysis

The format of configuration items in the flink-conf.yaml file is incorrect.

security.kerberos.login.principal:pippo

Solution

Modify the configurations in the flink-conf.yaml file and ensure that there is a space between a configuration item and its value.

security.kerberos.login.principal: pippo
