[jira] [Created] (HDFS-6512) Unnecessary synchronization on collection used for test

Benoy Antony created HDFS-6512:
----------------------------------

             Summary: Unnecessary synchronization on collection used for test
                 Key: HDFS-6512
                 URL: https://issues.apache.org/jira/browse/HDFS-6512
             Project: Hadoop HDFS
          Issue Type: Bug
          Components: security
            Reporter: Benoy Antony
            Assignee: Benoy Antony
            Priority: Minor


The function _SecurityUtil.getKerberosInfo()_  is a function used during authentication and authorization. 

It has two synchronized blocks and one of them is on testProviders. This is an unnecessary lock given that the testProviders is empty in real scenario.
