---------------------------------
Summary: AbstractHadoopProcessor can NPE when a configuration
issue happens
Key: NIFI-5962
URL: https://issues.apache.org/jira/browse/NIFI-5962
Project: Apache NiFi
Issue Type: Bug
Affects Versions: 1.8.0
Reporter: Bryan Bende
Assignee: Bryan Bende
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:
