From Hive

If the source link of a job is the Link to Hive, configure the source job parameters based on Table 1.

**Table 1** Parameter description
Parameter	Description	Example Value
Database Name	Database name. Click the icon next to the text box. The dialog box for selecting the database is displayed.	default
Table Name	Hive table name. Click the icon next to the text box. The dialog box for selecting the table is displayed. This parameter can be configured as a macro variable of date and time and a path name can contain multiple macro variables. When the macro variable of date and time works with a scheduled job, the incremental data can be synchronized periodically. For details, see Incremental Synchronization Using the Macro Variables of Date and Time. NOTE: If you have configured a macro variable of date and time and schedule a CDM job through DataArts Studio DataArts Factory, the system replaces the macro variable of date and time with (Planned start time of the data development job – Offset) rather than (Actual start time of the CDM job – Offset).	TBL_E
Read Mode	Two read modes are available: HDFS and JDBC. By default, the HDFS mode is used. If you do not need to use the WHERE condition to filter data or add new fields on the field mapping page, select the HDFS mode. The HDFS mode shows good performance, but in this mode, you cannot use the WHERE condition to filter data or add new fields on the field mapping page. The HDFS mode allows you to use the WHERE condition to filter data or add new fields on the field mapping page.	HDFS
Partition Filter Criteria	This parameter is displayed when you select the HDFS read mode and click Show Advanced Attributes. You can configure multiple values (separated by spaces) or a field value range. The time macro function is supported. For details, see Incremental Synchronization Using the Macro Variables of Date and Time. NOTE: If you have configured a macro variable of date and time and schedule a CDM job through DataArts Studio DataArts Factory, the system replaces the macro variable of date and time with (Planned start time of the data development job – Offset) rather than (Actual start time of the CDM job – Offset).	Single/Multi-value filtering: "${dateformat(yyyyMMdd, -1, DAY)} ${dateformat(yyyyMMdd)}" Filter by range: "${value} >= ${dateformat(yyyyMMdd, -7, DAY)} && ${value} < ${dateformat(yyyyMMdd)}"
WHERE Clause	This parameter is displayed when you select the JDBC read mode and click Show Advanced Attributes. This parameter indicates the WHERE clause to be extracted. If this parameter is not set, the entire table is extracted. If the table to be migrated does not contain the fields specified by the WHERE clause, the migration will fail. You can set a date macro variable to extract data generated on a specific date. For details, see Incremental Migration of Relational Databases. NOTE: If you have configured a macro variable of date and time and schedule a CDM job through DataArts Studio DataArts Factory, the system replaces the macro variable of date and time with (Planned start time of the data development job – Offset) rather than (Actual start time of the CDM job – Offset).	age > 18 and age <= 60
