Description

While running Hive(0.9.0) query over HBase(0.94.0) with hive-hbase-handler, there always throws a Null Pointer Exception on Scanner object. Since the TableInputFormatBase#createRecordReader() missed the initialization of TableRecordReader object. The scanner will be null in that case. This issue causes Hive query fails.
