Jonathan Albrecht commented on HBASE-27451:
-------------------------------------------
[~zhangduo] I had a look a the logs
(https://ci-hbase.apache.org/job/HBase-Nightly-s390x/50/artifact/output/junit.log)
for that last build. There was an OutOfMemoryError in the
org.apache.hadoop.hbase.regionserver.TestMemStoreLAB test. It seems to happen
frequently in previous Jenkins builds but it never happens on my test VM (where
I could reproduce the test hangs) even though it has less memory than the
Jenkins nodes. The OutOfMemoryError seems to happen only with this test so I'm
wondering if there might be something different about that test?
[~gmcdonald] [~cml] I was wondering if there might be any memory limits set
by the Jenkins agent or anything else on the Jenkins nodes that might cause
surefire tests to hang?
I didn't see anything else in the logs that seemed strange but it would be
great if anyone has some time to check it.
