Try these commands:

1. /usr/local/hadoop/bin$./stop-all.sh
(If hadoop is already running)

2. $sudo rm -Rf /app/hadoop/tmp/*
(This command will remove temporary files from hadoop)

3. /usr/local/hadoop/bin$hadoop namenode -format
(Format HDFS)

4. /usr/local/hadoop/bin$./start-all.sh
(Restart Hadoop)

5.$jps

Namenode 
Datanode
Jobtracker
Tasktracker
SecondaryNameNode

All these should be present

Title:
  Problems starting namenode with hadoop-conf-pseudo

Status in Hadoop Ubuntu Packages:
  Confirmed

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.
