]
Suresh Srinivas commented on HDFS-1891:
---------------------------------------
TestBackupNode failure is due to ipv6 address returned by java
Socket.getLocalSocketAddress(). The returned address 0:0:0:0:0:0:0:0:50100.
We need to disable IPV6 by setting system property java.net.preferIPv4Stack to
true,
as indicated in
http://download.oracle.com/javase/6/docs/technotes/guides/net/ipv6_guide/index.html
