             Summary: Improve HDFS processors provenance transit URL
                 Key: NIFI-4544
                 URL: https://issues.apache.org/jira/browse/NIFI-4544
             Project: Apache NiFi
          Issue Type: Improvement
          Components: Extensions
            Reporter: Koji Kawamura
            Assignee: Koji Kawamura


HDFS related processors report NiFi provenance events with transit URLs in a 
format as a Path in HDFS, e.g. '/user/nifi/21495865474943'. However, the URL is 
not descriptive enough if a NiFi interacts with multiple HDFS environments 
having the same paths.

HDFS processors transit URL should include host information it operates with, 
so that an URL can identify a HDFS environment. Also, those URLs should have 
'hdfs://' protocol so that external programs can understand a provenance event 
is performed against HDFS.

Target Processors:
* FetchHDFS
* FetchParquet
* GetHDFS
* GetHDFSSequenceFIle
* PutHDFS
* PutParquet
