We plan to migrate a 30 nodes hadoop 1.0.1 cluster to the version 2.3.0. We dont have extra machines to setup a separate new cluster, thus hope to do an in-place migration by replacing the components on the existing computers. So the questions are:

1) Is it possible to do an in-place migration, while keeping all data in HDFS safely?
2) If it is yes, is there any doc/guidance to do this?
3) Is the 2.0.3 MR API binary compatible with the one of 1.0.1?
