Subject [jira] Updated: (HDFS-1634) HDFS Federation: Convert single threaded DataNode into per BlockPool thread model.
Date Wed, 23 Feb 2011 20:12:38 GMT

     [ https://issues.apache.org/jira/browse/HDFS-1634?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Boris Shkolnik updated HDFS-1634:
---------------------------------

    Attachment: HDFS-1634-2.patch

This patch introduces new inner class for DataNode (BPOfferService), which implements Runnable
and one instance of which will be created per NameNode. Handshake, register and run loop is
moved to this class (thread), as well as some other methods that are per Namenode.

Patch also adds some configuration changes and some testing. These areas will be changed more
in future patches.
