Untangle depencencies between NN components -------------------------------------------
Key: HDFS-2223 URL: https://issues.apache.org/jira/browse/HDFS-2223 Project: Hadoop HDFS Issue Type: Improvement Components: name-node Affects Versions: 0.23.0 Reporter: Todd Lipcon Assignee: Todd Lipcon Working in the NN a lot for HA (HDFS-1623) I've come across a number of situations where the tangled dependencies between NN components has been problematic for adding new features and for testability. It would be good to untangle some of these and clarify what the distinction is between the different components: NameNode, FSNamesystem, FSDirectory, FSImage, NNStorage, and FSEditLog -- This message is automatically generated by JIRA.
