Description

Hi, we would like to create table that pulling HBase columns with regex matching. for example:
CREATE EXTERNAL TABLE XXX(
key string
, DATES MAP<STRING, BIGINT>
, FLOATS MAP<STRING, DOUBLE>
, STRINGS MAP<STRING, STRING>
)
STORED BY 'org.apache.hadoop.hive.hbase.HBaseStorageHandler' WITH SERDEPROPERTIES (
"hbase.columns.mapping" = ":key, FECF:D_[0-9]*, FECF:F_[0-9]*, FECF:C[0-9]*_[0-9]*",
"hbase.table.default.storage.type" = "binary")
TBLPROPERTIES ("hbase.table.name" = "XXX");

currently only prefix work (with hive 0.12.0):
CREATE EXTERNAL TABLE XXX(
key string
, DATES MAP<STRING, BIGINT>
, FLOATS MAP<STRING, DOUBLE>
, STRINGS MAP<STRING, STRING>
)
STORED BY 'org.apache.hadoop.hive.hbase.HBaseStorageHandler' WITH SERDEPROPERTIES (
"hbase.columns.mapping" = ":key, FECF:D_.*, FECF:F_.*, FECF:C.*",
"hbase.table.default.storage.type" = "binary")
TBLPROPERTIES ("hbase.table.name" = "XXX");
