Subject [jira] [Updated] (HDFS-3522) If NN is in safemode, it should throw SafeModeException when getBlockLocations has zero locations
Date Tue, 12 Jun 2012 03:17:43 GMT

     [ https://issues.apache.org/jira/browse/HDFS-3522?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Todd Lipcon updated HDFS-3522:
------------------------------

    Release Note: getBlockLocations(), and hence open() for read, will now throw SafeModeException
if the NameNode is still in safe mode and there are no replicas reported yet for one of the
blocks in the file.
    Hadoop Flags: Incompatible change,Reviewed  (was: Reviewed)

Marking as incompatible change, since this will now throw an exception for this where it didn't
before. I think it's fine, but we should call it out.
