In a case where data from multiple sources needs to be aggregated, what approach should be taken using Hadoop Streaming API for optimal results?
- Implement Multiple Reducers
- Implement a Single Mapper
- Use Combiners for Intermediate Aggregation
- Utilize Hadoop Federation
For optimal results in aggregating data from multiple sources with Hadoop Streaming API, the approach should involve using Combiners for Intermediate Aggregation. Combiners help reduce the amount of data transferred between mappers and reducers, improving overall performance in the aggregation process.
