how to know which part of the explain plan my MR job is running?
Yang 2012-06-24, 11:13
now my pig script is stuck at one of the MR jobs, in reduce stage,
it stayed in reducing state for 30minutes without much progress.

now, to debug this, how could I determine which part of the explain plan
represents
this MR job?
Thanks!
