What's the best way of implementing transaction management in HBase?  I have
a use case in which I update multiple tables.  If for some reason an update
fails on the 2nd table, I would like to rollback changes to the first
table.  A quick Google search got me to this document:
http://hbase.apache.org/docs/r0.20.6/api/org/apache/hadoop/hbase/client/transactional/TransactionManager.html

But this class is not available in 0.20.3 or in the latest version 0.90.3.

Please help.  Thanks.

This is now maintained for 0.90.RC3 on
https://github.com/hbase-trx/hbase-transactional-tableindexed/

I guess it is compatible with 0.90.3 (I plan to test it one of these days).

Tks,
Eric
