Review request for hadoop-hdfs.


Summary
-------

BookKeeper is a system to reliably log streams of records (https://issues.apache.org/jira/browse/ZOOKEEPER-276).
The NameNode is a natural target for such a system for being the metadata repository of the
entire file system for HDFS. 


This addresses bug HDFS-234.
