MsSqlToHiveOperator
Apache HiveMoves data from Microsoft SQL Server to Hive. The operator runs your query against Microsoft SQL Server, stores the file locally before loading it into a Hive table. If the create or recreate arguments are set to True, a CREATE TABLE and DROP TABLE statements are generated. Hive data types are inferred from the cursor’s metadata. Note that the table generated in Hive uses STORED AS textfile which isn’t the most efficient serialization format. If a large amount of data is loaded and/or if the table gets queried considerably, you may want to use this operator only to stage the data into a temporary table before loading it into its final destination using a HiveOperator.
Access Instructions
