Hadoop error can not start-all sh

Question

I have set all the properties and I am trying to start the Hadoop daemons. But I am getting the following error:

hduser@sepdau:/home/hadoop$ start-all.sh
mkdir: cannot create directory `/var/run/hadoop': Permission denied

Answer 1

Try adding

<property>
  <name>dfs.name.dir</name>
   <value>/path/to/hdfs/dir</value>
 </property>

to hdfs-site.xml and try again
