-----------------------------------------------------------------------------

Project: Hadoop
Issue Type: Bug
Components: dfs
Reporter: dhruba borthakur
Assignee: Hairong Kuang
These unit tests use a file /tmp.txt. This causes problems if I run two
instances of unit tests on two different workspaces concurrently.
