Subject CDH4 version questions
Date Tue, 19 Feb 2013 08:03:03 GMT
Hi User,

  We're facing the challenge of which hadoop version to choose.
  We prefer to CDH4, but have a few qustions:
  1.Are MRV1 and MRV2 sharing the  same hdfs? If so, can MRV1 upgrade to
MRV2 smoothly?
  2.If using MRV1, should our m/r code basing CDH3 be changed?
  3.Is MRV1 stable enough to be used in production?

Thanks & best regards,
Jing Wang
