Subject How to set "hadoop.tmp.dir" if I have multiple disks per node?
Date Mon, 16 Dec 2013 07:02:20 GMT
I have ten disks per node,and I don't know what value I should set to
"hadoop.tmp.dir". Some said this property refers to a location in local
disk while some other said it refers to a directory in HDFS. I'm confused,
who can explain it ?

I want to spread I/O since I have ten disks per node, so should I set a
comma-separated list of directories (which are on different disks) to
"hadoop.tmp.dir" ?
