Dear All Hadoop Users and Developers, I am planning on upgrading the cluster I'm working with from 0.12.1 to latest versions. I could find a link about upgrading in wiki ( http://wiki.apache.org/lucene-hadoop/Hadoop_Upgrade), but I was wondering if it applied to the upgrade from older versions like 0.12.x or earlier.
Has anybody done upgrade from 0.12.x? If so, would you mind sharing your joyful/painful experience with me? Or any tips and/or advices will be appreciated. Thank you in advance, Regards, -- Taeho Kang [tkang.blogspot.com] Software Engineer, NHN Corporation, Korea
