             Summary: delete hdfs processor throws an error stating transfer relationship not specified even when all relationships are present
                 Key: NIFI-3204
                 URL: https://issues.apache.org/jira/browse/NIFI-3204
             Project: Apache NiFi
          Issue Type: Bug
            Reporter: Arpit Gupta


Following flow was setup

get file -> extract text -> delete hdfs

A bunch of files were written each having one line which was the path to delete. Some of these path's were files, some were directories and some were patterns. Extract text would extract the line and assign to an attribute which delete hdfs would use to populate the path to delete.

However the processor would run into an error when ever it tried to process the path which was a pattern matching multiple paths.
