-----------------------------------------------------------------
Could the problem be IPv6-related? I'm getting this error when trying out the
configuration listed at
http://hadoop.apache.org/core/docs/current/quickstart.html#PseudoDistributed
Reading
http://www.michael-noll.com/wiki/Running_Hadoop_On_Ubuntu_Linux_(Single-Node_Cluster)#Disabling_IPv6,
I got the idea to explicitly set 127.0.0.1 instead of 0.0.0.0 for values where
this was the default.
I.e., I replaced 0.0.0.0 with 127.0.0.1 for dfs.secondary.http.address,
dfs.datanode.address, dfs.datanode.http.address, dfs.datanode.ipc.address,
dfs.http.address, dfs.datanode.https.address, dfs.https.address,
mapred.job.tracker.http.address, and mapred.task.tracker.http.address.
That solved the problem.

Reading http://wiki.github.com/klbostee/dumbo/short-tutorial, I got the idea to
explicitly set my real IPv4 address instead of 0.0.0.0 for values where this
was the default.
I.e., I replaced 0.0.0.0 with my real IP address for
dfs.secondary.http.address, dfs.datanode.address, dfs.datanode.http.address,
dfs.datanode.ipc.address, dfs.http.address, dfs.datanode.https.address,
dfs.https.address, mapred.job.tracker.http.address, and
mapred.task.tracker.http.address. Setting 127.0.0.1 would probably have worked
as well.
That solved the problem.
