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.
