Josh Elser commented on ACCUMULO-3708: -------------------------------------- [~afuchs], what's the context on the second stack trace? I don't see any Accumulo code. I can see the first one is about a failed MinC. > datanode blacklist error should be reclassified as a warning > ------------------------------------------------------------ > > Key: ACCUMULO-3708 > URL: https://issues.apache.org/jira/browse/ACCUMULO-3708 > Project: Accumulo > Issue Type: Bug > Affects Versions: 1.6.2 > Reporter: Adam Fuchs > Priority: Minor > > Saw the following exceptions when running a continuous ingest test.
