-----------------------------------
[~JPercivall] Anything other details you might be able to provide?
Unfortunately, this stack trace is not super informative. The stack traces are
happening in a web thread while the messages before/after are not.
Are there any other pages that are inaccessible?
While it shouldn't be related, what happens if you wait for the Provenance
Maintenance Thread to finish before attempting to access the UI?
> Problem accessing provenance initially when upgrading from 1.1.2 to 1.2.0
> -------------------------------------------------------------------------
>
> Key: NIFI-3839
> URL: https://issues.apache.org/jira/browse/NIFI-3839
> Project: Apache NiFi
> Issue Type: Bug
> Affects Versions: 1.2.0
> Environment: centos 7, docker instance, OpenJDK 1.8
> Reporter: Joseph Percivall
> Priority: Minor
>
> Upgraded a long running dev docker 1.1.2 instance to 1.2.0 RC1. Did not
> change any configuration. After leaving it running for a couple days, when I
> attempted to access provenance either by right-clicking the component or by
> accessing it through the hamburger menu I got a 500 error due to a NPE. I see
> the stacktrace in the window that should have the provenance events
> (stacktraces from nifi-app log below). Upgraded the version to RC2
> (restarting the container) and afterwards it worked.
> There are no tickets resolved in RC2 that appear to relate to this issue.
> One thing of note relating to provenance, there would have been events that
> expired between being started with 1.2.0-RC1 and the provenance being queried.
> The docker container was running the latest version of Centos7 with OpenJdk
> java 1.8.0 and the provenance volume was mounted (so it persisted through
> restarts). Also, the instance is secure with certs and I had the correct
> policies to access the provenance.
> I have not been able to reproduce and restarting the instance appeared to
> resolve the issue. I am logging an issue relating to the RC because I believe
> there may be an issue related to upgrading 1.1.2 -> 1.2.0 and provenance
> events expiring while keeping an old prov repo but is solved by restarting.
> For the stacktraces, I pulled a couple lines before/after the actual
> stacktrace in order to provide context and maybe some pertinent context.
