Sadly no. We just moved forward unsecure and anonymous login to nifi-reg. Securing more from the outside instead of internal to the environment. Basically coming up with a comment format to identify who is making the change.

I am currently running NiFi 1.6.0 and NiFi Registry 0.1.0 in the official apache docker containers and both boot up with zero errors. My problem occurs when I try to Start Version Control on a Processor Group: "Unable to obtain listing of buckets: java.net.ConnectException: Connection refused (Connection refused)" I followed the guide: https://community.hortonworks.com/content/kbentry/171173/setting-up-a-secure-nifi-to-integrate-with-a-secur.html I am using the same sys_admin cert for both containers and I am able to login just fine. My nifi-registry-app.log shows this entry when I try to start version control: "[NiFi Registry Web Server-17] o.a.n.r.w.m.IllegalStateExceptionMapper java.lang.IllegalStateException:
Kerberos service ticket login not supported by this NiFi Registry. Returning Conflict response." Please let me know what additional information I should include. nifi-connect-error.png nifi-reg-log.png

I am a bit of a neat freak and love that I can now align processors and groups on the GUI, but while I'm double clicking on them they sometimes move slightly. Is there any way to pin them to the grid and stop them from moving?

I also tried an UpdateAttribute processor (without pulling the filename from report.attachment): filename : ${filename}.docx That worked successfully and wrote 4932780329353.docx to disk.

@Shu Between InvokeHTTP and PutFile, I inserted UpdateAttribute with filename : ${report.url:substringAfterLast('/')} It shows successful modification: filename
Sample2.docx 4932780329353 (previous) It even identifies mime.type application/vnd.openxmlformats-officedocument.wordprocessingml.document But will not PutFile. PutFile drops the file due to failure Relationship. When I remove the UpdateAttribute processor it successfully writes to disk but with the 4932780329353 filename.

I am trying to update an attribute (report.url) which is the full url path to a file "https://domain.com/report/foo.txt" so I can set the filename in my UpdateAttribute processor before writing the file to disk. report.url is set during an EvaluteXQuery processor "//item/link" During EvaluteXQuery, could I set another attribute to be a substring of "//item/link" ? Goal: Update filename attribute to "foo.txt" prior to PutFile processor.

@Wynner No, they are all independent and each of the first 4 just remove one tag/string per flowfile. One will remove URL attribute from an XML tag <FOOBAR xmlns="http://example.com">(one per flowfile), another will remove the <!DOCTYPE tag, remove <xml version> tag, etc, and the last one prepends <Message> to the front and appends </Message> to the end.

I am ingesting a ton of slightly malformed streaming XML messages which require 5 ReplaceText processors to make pretty and able to be parsed. Is there a simple solution to combining them into one processor?
