Does the EMR Hadoop input connector for Kinesis enable continuous stream processing?

  1. Only in some regions
  2. Yes
  3. No
  4. Only if the iteration process succeeds

Answer(s): C

Explanation:

The Hadoop MapReduce framework is a batch processing system. As such, it does not support continuous queries. However, there is an emerging set of Hadoop ecosystem frameworks like Twitter Storm and Spark Streaming that enable developers to build applications for continuous stream processing. A Storm connector for Kinesis is available on GitHub here and you can find a tutorial explaining how to setup Spark Streaming on EMR and run continuous queries here.
Additionally, developers can utilize the Kinesis client library to develop real-time stream processing applications.
