Dear all,

I am a new Hadoop learner. The version I used is 1.0.0.

I tried to set a new value for the parameter instead of /tmp,
hadoop.tmp.dir in core-site.xml, hdfs-site.xml and mapred-site.xml. Do I
need to do that in all the above xmls?

However, when I execute the format command, I was asked if I need to
reformat filesystem in /tmp/hadoop-myname/dfs/name. Why is the path still
/tmp?

Thanks,
Bing

Hi Bing
      What is yout value for dfs.name.dir and dfs.data.dir ? I believe that is still pointing to /tmp. Better to change it to another location as /tmp gets wiped on every reboot.
