The hadoop-conf-pseudo package is a bit racey in that it depends on
hadoop-namenode - however if the namenode has not finished deciding it
can't start by the time hadoop-conf-pseudo formats the namenode
filesystem the format fails and then the namenode won't start anyway.

Running:

sudo su hdfs -c "hadoop namenode -format"

Without the namenode running should workaround the issue

Title:
  Problems starting namenode with hadoop-conf-pseudo

Status in Hadoop Ubuntu Packages:
  New

Bug description:
  I've installed the hadoop-config-pseudo package.

  It looks like the namenode is failing to start and the below is from
  the namenode log. I've checked, and the directory does exist. Anything
  else I should check? The system is running precise.
