             Summary: TestJournalNodeRespectsBindHostKeys#testHttpsBindHostKey very flaky
                 Key: HDFS-16002
                 URL: https://issues.apache.org/jira/browse/HDFS-16002
             Project: Hadoop HDFS
          Issue Type: Bug
            Reporter: Wei-Chiu Chuang


This test appears to be failing a lot lately. I suspect it has to be with the new change to support reloading httpserver2 certificates, but I've not looked into it.
