I was trying to configure a PutHDFS processor to connect to a kerberized HDFS cluster, and because of an issue with the kerberos config, the login during onScheduled failed and resulted on the configuration instance not being fully constructed, and then going into onStopped and encountering a NullPointerException:
{code:java}
