Hi Harsh,

Tks for your quick reply, and sorry to be so late.

http://search-hadoop.com/m/gLWelrO8Mc helped me to find the Launch 
configuration for hadoop-hdfs and hadoop-mapreduce, but there are no 
such Launch config for hadoop-common.

Never mind, I just replaced :hdfs with :common and got [1].

My test success % has made an impressive jump, but I still have a few 
failures for example:
junit.framework.AssertionFailedError: -expunge failed expected:<0> but 
	at org.apache.hadoop.fs.TestTrash.trashShell(TestTrash.java:328)
	at org.apache.hadoop.fs.TestTrash.trashShell(TestTrash.java:102)
	at org.apache.hadoop.fs.TestTrash.testTrash(TestTrash.java:447)

About the needed environment variables to run the tests:

1.- Should the Launch configs be documented on 
http://wiki.apache.org/hadoop/EclipseEnvironment ?

2.- should Launch config be created for hadoop-common project ?

2.- The tests depend heavily on env variables. I wonder how to handle 
this with the upcoming maven structure 
(https://issues.apache.org/jira/browse/HADOOP-6671). Should we forsee 
during the test setUp() some default values, a bit like if we would 
generalize https://issues.apache.org/jira/browse/HADOOP-5916 
(Standardize fall-back value of test.build.data for testing directories) 
to all needed env.

Maybe this is already a know topic?
