I recently installed hadoop2.2.0 on my desktop running :

 Linux livingstream 3.2.0-29-generic #46-Ubuntu SMP Fri Jul 27 17:03:23 UTC 2012 x86_64 x86_64 x86_64 GNU/Lin

I am able to format the namenode just fine , however when I start the namenode using the following command:

hadoop-daemon.sh start namenode

I get the following permission errors , can anyone please help me with these errors:

   hduser@livingstream:/usr/local/hadoop$ hadoop-daemon.sh start namenode
 mkdir: cannot create directory `/var/run/hadoop': Permission denied
 starting namenode, logging to /var/log/hadoop/hduser/hadoop-hduser-namenode-  livingstream.out
 /usr/sbin/hadoop-daemon.sh: line 138: /var/run/hadoop/hadoop-hduser-namenode.pid: No such file or directory

Can you please help me with these errors.

Best Regards, Ishan
