At a glance, anyone can randomly label Spark a winner considering the … MapReduce and Spark are compatible with each other and Spark shares all MapReduce’s compatibilities for data sources, file formats, and business intelligence tools via JDBC and ODBC. Difference Between MapReduce and Spark. Map Reduce is an open-source framework for writing data into HDFS and processing structured and unstructured data present in HDFS. Also, we can say that the way they approach fault tolerance is different. After getting off hangover how Apache Spark and MapReduce works, we need to understand how these two technologies compare with each other, what are their pros and cons, so as to get a clear understanding which technology fits our use case. Spark’s Major Use Cases Over MapReduce . An open source technology commercially stewarded by Databricks Inc., Spark can "run programs up to 100x faster than Hadoop MapReduce in memory, or 10x faster on disk," its main project site states. Spark is newer and is a much faster entity—it uses cluster computing to extend the MapReduce model and significantly increase processing speed. But, unlike hardcoded Map and Reduce slots in TaskTracker, these slots are generic where any task can run. Spark vs Hadoop MapReduce: In Terms of Performance. Comprises simple Map and Reduce tasks: Suitable for: Real-time streaming : Batch processing: Coding: Lesser lines of code: More … Hadoop uses replication to achieve fault tolerance whereas Spark uses different data storage model, resilient distributed datasets (RDD), uses a clever way of guaranteeing fault tolerance that minimizes network I/O. 2. Hadoop MapReduce: MapReduce writes all of the data back to the physical storage medium after each operation. It’s an open source implementation of Google’s MapReduce. Spark vs Hadoop is a popular battle nowadays increasing the popularity of Apache Spark, is an initial point of this battle. MapReduce vs Spark. Speed.
