Data Processing Rule
- The field values are exported to the Hive table.
- If one or more columns are specified as partition columns, the Partition Handlers feature is displayed on the To page in Step 4 of the job configuration. Partition Handlers specifies the number of handlers for processing data partitioning.
- If no column is designated as partition columns, input data does not need to be partitioned, and Partition Handlers is hidden by default.
Example
Use the CSV File Input operator to generate two fields A and B.
The following figure shows the source file.
Configure the Hive Output operator to export a_str and b_str to the Hive table.
After the execution is complete, view the table data.
