Subject [jira] Created: (HDFS-1222) NameNode fail stop in spite of multiple metadata directories
Date Thu, 17 Jun 2010 04:00:23 GMT
NameNode fail stop in spite of multiple metadata directories

                 Key: HDFS-1222
                 URL: https://issues.apache.org/jira/browse/HDFS-1222
             Project: Hadoop HDFS
          Issue Type: Bug
          Components: name-node
    Affects Versions: 0.20.1
            Reporter: Thanh Do

Despite the ability to configure multiple name directories
(to store fsimage) and edits directories, the NameNode will fail stop 
in most of the time it faces exception when accessing to these directories.
NameNode fail stops if an exception happens when loading fsimage,
reading fstime, loading edits log, writing fsimage.ckpt ..., although there 
are still good replicas. NameNode could have tried to work with other replicas,
and marked the faulty one.

This bug was found by our Failure Testing Service framework:
