> Added support for pulling hbase columns just by providing prefixes and a wildcard. So a query now could look something like this:

> CREATE EXTERNAL TABLE hive_hbase_test
> ROW FORMAT SERDE 'org.apache.hadoop.hive.hbase.HBaseSerDe'
> STORED BY 'org.apache.hadoop.hive.hbase.HBaseStorageHandler'
> WITH SERDEPROPERTIES ("hbase.columns.mapping" = ":key,fam1:col*")
> TBLPROPERTIES ("hbase.table.name" = "TEST_HBASE_TABLE");

> This would pull in all columns under column family "fam1" which start with "col". This gives a little more flexibility over pull all columns format.
