Subject [jira] [Resolved] (HDFS-5149) Support for federated cache pools
Date Wed, 22 Jan 2014 21:56:44 GMT

     [ https://issues.apache.org/jira/browse/HDFS-5149?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Andrew Wang resolved HDFS-5149.

    Resolution: Incomplete

I think we can just resolve this, since the above agreement seems to be that there isn't anything
to do. Please reopen or file a new JIRA if something comes up, thanks!

>             Project: Hadoop HDFS
>          Issue Type: Sub-task
>          Components: datanode, namenode
>    Affects Versions: HDFS-4949
>            Reporter: Andrew Wang
>            Assignee: Andrew Wang
> The federation concept of a "blockpool" has not pervaded the caching implementation thus
far, e.g. datanodes do not track and report usage by block pool, some namenode operations
are not block pool aware. This requires re-examination of protobufs / protocol / handling
