From: Bing Li To: common-user@hadoop.apache.org Content-Type: multipart/alternative; boundary=e0cb4efe2e5218afbe04b85198b6 --e0cb4efe2e5218afbe04b85198b6 Content-Type: text/plain; charset=ISO-8859-1 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 --e0cb4efe2e5218afbe04b85198b6--
