Subject IO pipeline optimizations
Date Tue, 19 Jul 2011 20:26:28 GMT
This blog post on YDN website
http://developer.yahoo.com/blogs/hadoop/posts/2009/08/the_anatomy_of_hadoop_io_pipel/has
detailed discussion on different steps involved in Hadoop IO
operations
and opportunities for optimizations. Could someone please comment on current
state of these potential optimizations? Are some of these expected to be
addressed in "next gen MR" release?

Thanks,
-Shrinivas
