Key: HDFS-14731
URL: https://issues.apache.org/jira/browse/HDFS-14731
Project: Hadoop HDFS
Issue Type: Sub-task

Currently NameNode has two global locks: FSNamesystemLock and FSDirectoryLock.
An analysis shows that single FSNamesystemLock is sufficient to guarantee
consistency of the NameNode state. FSDirectoryLock can be removed.
