Apache Spark
MapReduce
Spark processes data in batches as well as in real-time
MapReduce processes data in batches only
Spark runs almost 100 times faster than Hadoop MapReduce
Hadoop MapReduce is slower when it comes to large scale data processing
Spark stores data in the RAM i.e. in-memory. So, it is easier to retrieve it
Hadoop MapReduce data is stored in HDFS and hence takes a long time to retrieve the data
Spark provides caching and in-memory data storage
Hadoop is highly disk-dependent
