Subject [jira] [Updated] (HDFS-5200) Datanode should have compatibility mode for sending combined block reports
Date Fri, 13 Sep 2013 20:37:52 GMT

     [ https://issues.apache.org/jira/browse/HDFS-5200?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Arpit Agarwal updated HDFS-5200:
--------------------------------

    Description: We may want to consider adding a compatibility mode to the Datanode wherein
it can send a combined block report (as is done today). HDFS-4988 will modify this behavior
so that the Datanode will send one block report per Storage Directory. We will look at this
when we get to compatibility/upgrade testing for the feature.
