HADOOP-7949 [junit] Test org.apache.hadoop.ipc.TestSaslRPC FAILED
[junit] Test org.apache.hadoop.metrics2.impl.TestGangliaMetrics FAILED
On further inspection, the TestSaslRPC failure was tracked down to HADOOP-7949 and the need for localhost to appear before localhost.localdomain in the /etc/hosts file.
Wow, just wow.
It shouldn't be this difficult to set up a build environment. I've resorted to going to the hadoop dev mailing lists to see if anyone can help with the last one.
