Hi,

I am posting for the first time. Please let me know if this needs to go to
any other mailing list.

I am trying to build Hadoop from source code, and I am able to successfully
build until the Hadoop-Common-Project. However, in case of HDFS the test
called "TestHftpURLTimeouts" is failing intermittently. Please note that
when I run the test individually, it passes. I have taken care of all steps
given in HowToContribute twiki page of Hadoop. Please let me know ,

1. Whether this kind of behaviour is expected
2. Can this intermittent test case failure be ignored.
3. Will it be a reliable build if I use the -DskipTests option in mvn
command

 Adding build results below for the following command : mvn -e  package
-Pdist,native -Dtar

Results :

Failed tests:
testHftpSocketTimeout(org.apache.hadoop.hdfs.TestHftpURLTimeouts):
expected:<connect timed out> but was:<null>

Tests run: 705, Failures: 1, Errors: 0, Skipped: 3
