  Please add requirements as sections below.

not need to provide non-java clients but we should be able to support them before going to
2.0.

servers clearly don't implement.

with much better future-proof APIs. The current Map/Reduce interface needs to be removed.

  This was agreed to in a [http://markmail.org/message/flljdfpgj65zngsf thread on general@].
 There will be three separate projects, mapred, hdfs, and a library of common APIs and utilities
