Despite having that fix, we are seeing this issue in a > 2.4.6-based deploy. We recently started seeing it as we were moving to > centos8. I'm not sure why the centos version would affect this, otherwise the > hbase server version and java versions were not changing. > We're seeing this in a non-trivial number of new centos8 servers that we spin > up. I'm pushing a hotfix which removes RegionInfo.UNDEFINED to see if that > resolves our issue. > As mentioned in my last comments on that jira, it could be that this field is > still an issue because according to > [https://stackoverflow.com/questions/28631656/runnable-thread-state-but-in-object-wait:] > > Such deadlocks may be caused by a [typical > > bug|https://bugs.openjdk.org/browse/JDK-8037567] when a subclass is > > referenced from a static initializer. > If that's true, in this case MutableRegionInfo is a subclass/implementer of > RegionInfo, so that could trigger it. Granted the linked bug is marked "Not > An Issue". -- This message was sent by Atlassian Jira (v8.20.10#820010)
