Review request for hcatalog, Francis Liu and David Capwell.
Changes
-------
Updated the summary and jira number for the review.
Summary (updated)
-------
A revision manager for HBase would provide revision numbers for each of the
record written using HBase output storage driver in place of timestamps. In
addition, the revision manager provides capabilities to take snapshots of HBase
tables. Snapshots help in achieving repeatable reads which is a requirement for
map-reduce paradigm. This patch contains all the core classes for the revision
management.
This addresses bug hcatalog-189.
