Subject Re: io.sort.mb configuration?
Date Tue, 22 Dec 2009 17:17:27 GMT
Hadoop has a default file (hadoop-default.xml - version 19) for all
configuration, don't change the values in that file (they won't be
affected), copy the parameter to the file hadoop-site.xml where you
set up the cluster and set the value you want there.
