Summary: GetFTP NullPointerException on 1.1.1
Key: NIFI-3595
URL: https://issues.apache.org/jira/browse/NIFI-3595
Project: Apache NiFi
Issue Type: Bug
Affects Versions: 1.1.1
Environment: API version is 0.6.1 and deployed on 1.1.1
Reporter: Mahfuzul Amin
GetFTP processor throws NullPointerException randomly on 1.1.1. Recently we
have installed the version 1.1.1. We have another server where nifi version
0.6.1 is running. According to our observation GetFTP works fine on version
0.6.1. To replicate the flows we have copied the flow.xml.gz file from nifi
0.6.1 to 1.1.1.Our custom processors are using the API version 0.6.1 in the
project. The stacktarce is given below:
