-----------------------------------------

             Summary: Storage class member storageDirs should be private to 
avoid unprotected access by derived classes
                 Key: HDFS-11287
                 URL: https://issues.apache.org/jira/browse/HDFS-11287
             Project: Hadoop HDFS
          Issue Type: Bug
            Reporter: Manoj Govindassamy
            Assignee: Manoj Govindassamy


HDFS-11267 fix made the abstract class Storage.java member variable storageDirs 
a thread safe one so that all its derived classes like NNStorage, JNStorage, 
DataStorage will not face any ConcurrentModificationException when there are 
volume add/remove and listing operations running in parallel. The fix rebase 
missed out few changers to the original patch. This jira is to address the 
addendum needed for the HDFS-11267 commits.
