Here is my official +1. I executed the same tests from 1.1.3RC for 1.0.3RC.
- checked crcs, sigs. - checked tarball layouts, files, jar files, etc. - checked the book in the bin tar - checked versions reported - checked the compat report - compiled with Hadoop 2.2 to 2.7 - build with hbase-downstreamer - run local model, shell smoke tests, LTT. - Put it up on a 4 node cluster, ran LTT. Everything looks nominal.
