Ivan Kelly resolved HDFS-1489. ------------------------------ Resolution: Incomplete Assignee: Ivan Kelly This is now being handled by HDFS-1580 in a less monolithic fashion. > breaking the dependency between FSEditLog and FSImage > ----------------------------------------------------- > > Key: HDFS-1489 > URL: https://issues.apache.org/jira/browse/HDFS-1489 > Project: Hadoop HDFS > Issue Type: Improvement > Components: name-node > Affects Versions: 0.21.0 > Reporter: Diego Marron > Assignee: Ivan Kelly > Attachments: HDFS-1489.diff, HDFS-1489.diff, HDFS-1489.pdf, > NNStorage.diff, NNStorage.diff, NNStorage.diff, hdfs_1489.pdf > > > This is a refactor patch which its main concerns are: > - breaking the dependency between FSEditLog and FSImage > - Splitting the abstracting the error handling and directory management, > - Decoupling Storage from FSImage. > In order to accomplish the above goal, we will need to introduce new classes: > - NNStorage: Will care about the storage. It extends Storage class, and will > contain the StorageDirectories. > - NNUtils: Some utility static methods on FSImage and FSEditLog will be > moved here. > - PersistenceManager: FSNameSystem will now be responsible for managing the > FSImage & FSEditLog objects. There will be some logic that will have to moved > out of FSImage to facilite this. For this we propose a PersistanceManager? > object as follows. > For more deep details, see the design document uploaded. -- This message is automatically generated by JIRA. - For more information on JIRA, see: http://www.atlassian.com/software/jira
