[jira] [Created] (NIFI-3068) NiFi can only be configured for one HDFS clusters per installation

Sam Hjelmfelt created NIFI-3068:
-----------------------------------

             Summary: NiFi can only be configured for one HDFS clusters per installation
                 Key: NIFI-3068
                 URL: https://issues.apache.org/jira/browse/NIFI-3068
             Project: Apache NiFi
          Issue Type: Bug
          Components: Core Framework
    Affects Versions: 1.0.0
            Reporter: Sam Hjelmfelt


The HDFS configurations in PutHDFS are not respected when two (or more) PutHDFS processors exist with different configurations. The second processor to run will use the configurations from the first processor. This can cause data to be written to the wrong cluster.

This appears to be caused by configuration caching in AbstractHadoopProcessor, which would affect all HDFS processors.
