Subject [jira] Created: (HADOOP-1396) FileNotFound exception on DFS block
Date Mon, 21 May 2007 11:21:16 GMT
FileNotFound exception on DFS block
-----------------------------------

                 Key: HADOOP-1396
                 URL: https://issues.apache.org/jira/browse/HADOOP-1396
             Project: Hadoop
          Issue Type: Bug
          Components: dfs
    Affects Versions: 0.12.3
            Reporter: Devaraj Das
             Fix For: 0.14.0


Got a couple of exceptions of the form illustrated below. This was for a randomwriter run
(and every node in the cluster has multiple disks).

java.io.FileNotFoundException: /tmp/dfs/data/tmp/client-8395631522349067878 (No such file
or directory)

So it seems like the bug reported in HADOOP-758 still exists.
