All

for some reason when I run the format on the namenode it just hangs

I see the process running

theabyss:$ ps -ef|grep hadoop
  502 37859 33043   0 10:19am ttys006    0:00.00 grep hadoop
  503 37831 37395   0 10:19am ttys009    0:00.00 sh hadoop_admin.sh format
  503 37838 37831   0 10:19am ttys009    0:00.01 bash /apps/celertech/deployments/releases/current/services/hadoop-0.20.203.0/bin/hadoop -x namenode -format
  503 37855 37838   0 10:19am ttys009    0:00.00 bash /apps/celertech/deployments/releases/current/services/hadoop-0.20.203.0/bin/hadoop -x namenode -format
  503 37856 37855   0 10:19am ttys009    0:04.80 /usr/bin/java -Xmx32m org.apache.hadoop.util.PlatformName
theabyss:$

But the command line shows not output. Is there a way to debug this?

Ben,

Why are there two processes trying a format?

You may jstack their PIDs to see where they are hung.

Once I try and run jstack on it the  process does look like it attempts to start
