title: hadoop daemons not starting
body: <p>I have installed Hadoop in linux cluster. When I try to start the server by the command 
  $bin/start-all.sh, I get following errors:</p>
  
  <pre><code>mkdir: cannot create directory `/var/log/hadoop/spuri2': Permission denied
  chown: cannot access `/var/log/hadoop/spuri2': No such file or directory
  /home/spuri2/spring_2012/Hadoop/hadoop/hadoop-1.0.2/bin/hadoop-daemon.sh: line 136: /var/run/hadoop/hadoop-spuri2-namenode.pid: Permission denied
  head: cannot open `/var/log/hadoop/spuri2/hadoop-spuri2-namenode-gpu02.cluster.out' for reading: No such file or directory
  localhost: /home/spuri2/.bashrc: line 10: /act/Modules/3.2.6/init/bash: No such file or directory
  localhost: mkdir: cannot create directory `/var/log/hadoop/spuri2': Permission denied
  localhost: chown: cannot access `/var/log/hadoop/spuri2': No such file or directory
  </code></pre>
  
  <p>I have configured log directory parameter in conf/hadoop-env.sh to a /tmp directory and also I have configured the "hadoop.tmp.dir" in core-site.xml to /tmp/ directory. Since I do not have access to /var/log directory but still hadoop daemons are trying to write to /var/log directory and failing. </p>
  
  <p>I am wondering why this is happening?</p>
