[ https://issues.apache.org/jira/browse/NIFI-3927?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16014459#comment-16014459 ]

----------------------------------------------------------
I can not expect to have pipe at the end of every segment, because these messages are generated by other application. Moreover I have tried adding pipe at the end of every segment and still it didn't behave as expected. I am not sure how I am going to add CRLF characters after every segment.
Just tried to parse below message:

Every segment ends with pipe (|) and no segment repeated..

> I have an HL7 file which I want to put in HBase, So I am parsing this file through ExtractHL7Attributes processor. With the default value for every property processor works with no error but resultant attributes file only have one segment. When I sets `Use Segment Names` property true it throws NULLPointerException.
