Description

Hadoop 1.0 has been discussed in email alias [e-mail]
and in the wiki http://wiki.apache.org/hadoop/Release1.0Requirements
The discussion is summarized in this and in sub jiras. Further discussions will occur here rather than on email.

Below are the 4 main Hadoop 1.0 task categories that have been identified so far.

1. Decide on the Hadoop 1.0 compatibility requirements (HADOOP-xxx)
2. interface Classification - visibility (public/private) and stability (HADOOP-xxx)
3. Interface cleanup (HADOOP-xxx)
4. Mechanisms to support versioning and compatibility
5. 1.0 Features
   A few features that we need before 2.0 and are likely to break 1.0 compatibility; hence we should do them by 1.0
   • Security (HADOOP-4487)
   • Client recovery from NN (HADOOP-5062) retarts and JT restarts (HADOOP-5063)
