Summary: Remove the unnecessary writeLock while initializing CacheManager in FsNameSystem Ctor Key: HDFS-5665 URL: https://issues.apache.org/jira/browse/HDFS-5665 Project: Hadoop HDFS Issue Type: Improvement Components: namenode Affects Versions: 2.2.0, 3.0.0 Reporter: Uma Maheswara Rao G Assignee: Uma Maheswara Rao G I just saw the below piece of code in Fsnamesystem ctor. {code} writeLock(); try { this.cacheManager = new CacheManager(this, conf, blockManager); } finally { writeUnlock(); } {code} It seems unnecessary to keep writeLock here. I am not sure if there is a clear reason to keep the lock. -- This message was sent by Atlassian JIRA (v6.1.4#6159)
