Subject [jira] [Created] (HDFS-3661) SecondaryNameNode should be able to tolerate local directory failures
Date Sat, 14 Jul 2012 18:10:34 GMT
Eli Collins created HDFS-3661:
---------------------------------

             Summary: SecondaryNameNode should be able to tolerate local directory failures
                 Key: HDFS-3661
                 URL: https://issues.apache.org/jira/browse/HDFS-3661
             Project: Hadoop HDFS
          Issue Type: Bug
          Components: name-node
    Affects Versions: 2.0.0-alpha
            Reporter: Eli Collins


If the 2NN eg fails to write to one of its local checkpoint dirs while downloading an image
(eg due to the dir failing because it's out of space etc) the entire checkpoint will fail
even though there are other valid checkpoint directories. We should add local directory failure
toleration and restoration (similar to the NN).
