What have you tried already? Jenkins reran the test and it passed the second time.

Additional context I don't think I've ever seen this test fail before. It could have been a fluke.

Just for reference, I have been periodically running this IT past week or so and I have yet to see it fail.

I'm thinking we might be able to close this as OBE.

[ctubbsii]

Haven't seen it in awhile. Will close.

I am not sure if it this problem, or a similar issue with getting the instance id from hdfs but running the full tests with github actions, sometimes there are issues with the test getting the instance id.

One stack trace I could find (run on Jun 10):

[ERROR] Tests run: 1, Failures: 0, Errors: 1, Skipped: 0, Time elapsed: 27.464 s <<< FAILURE! - in org.apache.accumulo.test.functional.CombinerIT

[ctubbsii]

Hmm, that does look related.

[ctubbsii]

Closing, as I haven't seen this in awhile.
