Hello, I wonder how did the Yahoo! developers generate the Task Timeline figures in their "Hadoop Sorts a Petabyte..." blog post:
http://developer.yahoo.net/blogs/hadoop/2009/05/hadoop_sorts_a_petabyte_in_162.html I am interested to know the following two aspects: 1. How did they collect the data, 2. What software did they use to generate the image. Thanks, Rares P.S. I posted a comment on their blog, but I did not get any reply yet.
