Review request for hive.
Description
-------
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_NEW_KEPLER_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.
This addresses bug HIVE-3725.
