Luca Telloli updated HDFS-234:
------------------------------

    Attachment: HDFS-234.patch


This patch contains code for adding logging on Bookkeeper. This patch by itself 
requires HDFS-311 and its dependencies to be applied first and it's mainly for 
review and test. 
To simplify things, people interested in the Bookkeeper functionality can 
simply download the patch marked with -complete in the HDFS-311 which contains 
all the dependencies and applies against trunk.

> 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.
