Subject [jira] [Created] (HADOOP-7964) Deadlock in class init.
Date Sat, 07 Jan 2012 00:05:41 GMT
Deadlock in class init.
-----------------------

                 Key: HADOOP-7964
                 URL: https://issues.apache.org/jira/browse/HADOOP-7964
             Project: Hadoop Common
          Issue Type: Bug
          Components: security, util
    Affects Versions: 1.0.0, 0.20.205.0, 0.24.0, 0.23.1, 1.1.0
            Reporter: Kihwal Lee
            Priority: Blocker


After HADOOP-7808, client-side commands hang occasionally. There are cyclic dependencies in
NetUtils and SecurityUtil class initialization. Upon initial look at the stack trace, two
threads deadlock when they hit the either of class init the same time.
