Subject Hadoop Job Profiling Tool
Date Mon, 09 Jul 2012 22:37:41 GMT
Is there any Hadoop specific tool that can profile a job time? For
instance, if a job took x amount of time, the tool can profile how
this time was consumed at different stage likes time spent to read, to
 map, to reduce reduce , shuttle move that and the different steps of
a Hadoop M/R job?

If not, how do you recommend finding the map/reduce job bottle neck?
