Subject Re: [DISCUSS] Hive and HBase dependency
Date Fri, 14 Aug 2015 18:12:27 GMT
Thanks Alan. I created [1] to revert the non-passive changes from 1.x.

Out of curiosity, what are your plans on merging the metastore branch to
master? It seems like some coordination might be needed as some of the
stuff in the hive hbase integration might need some massaging before that
is done.
