Subject [jira] Updated: (HADOOP-1578) Data-nodes should send storage ID to the name-node during registration
Date Tue, 10 Jul 2007 02:04:05 GMT

     [ https://issues.apache.org/jira/browse/HADOOP-1578?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Konstantin Shvachko updated HADOOP-1578:
----------------------------------------

    Attachment: NeedStorageID2.patch

In order to prevent from happening that again I included
# an assert that verifies storage id consistency
# a log message when a new storage id is assigned, and
# an exception if the storage ids are not consistent.
