James Wing commented on NIFI-2115:
----------------------------------

[~rmoran], I agree that changes to the About dialog should be modest.  It may 
not be obvious from the screenshot in the PR, but initial impact to the About 
dialog in my code so far is just "..." following the version, which expands the 
detail info on click.

I had not considered the System Diagnostics dialog, but that may be a good 
idea.  We would have plenty of real estate on a new tab there.  The downside is 
that it is tucked away a bit, and the version in the about dialog will appear 
to be complete.  Maybe we could link from About to the System Diagnostics for 
detail?

Cluster versions are still not clear to me.  The version information appears to 
be particular to whichever API endpoint you happen to be talking to.  I think 
you are correct that we would need to enumerate the nodes and their respective 
versions.

>             Project: Apache NiFi
>          Issue Type: Improvement
>          Components: Core UI, Tools and Build
>    Affects Versions: 1.0.0

>            Priority: Minor

> The UI's About dialog and underlying API provide the version of NiFi, like 
> "0.7.0-SNAPSHOT".  For many bug reports and troubleshooting requests, this is 
> not very precise, especially around rapidly changing code or 
> platform-dependent behavior.  It would help if NiFi captured and displayed 
> additional information:  
> * NiFi build commit hash
> * NiFi build branch
> * NiFi build date/time
> * Java Version
> * Java Vendor (Oracle, OpenJDK)
> * OS
> Then a simple copy/paste from the about box would provide very specific 
> information about a particular NiFi installation and which code it was 
> derived from.
