Effective in version 10.2, the AllHiveSourceTables row in the Summary Statistics view in the Administrator tool includes records read from the following sources:
- Original Hive sources in the mapping.
- Staging Hive tables defined by the Hive engine.
- Staging data between two linked MapReduce jobs in each query.
If the LDTM session includes one MapReduce job, the AllHiveSourceTables statistic only includes original Hive sources in the mapping.
For more information, see the "Monitoring Mappings in the Hadoop Environment" chapter of the
Big Data Management 10.2 User Guide.
