Hadoop v/s Spark

1. Introduction to Apache Spark:
It is a framework for performing general data analytics on distributed computing cluster like Hadoop.It provides in memory computations for increase speed and data process over mapreduce.It runs on top of existing hadoop cluster and access hadoop data store (HDFS), can also process structured data in Hive and Streaming data from HDFS, Flume, Kafka, Twitter.
2. Is Apache Spark going to replace Hadoop?
Hadoop is parallel data processing framework that has traditionally been used to run map/reduce jobs. These are long running jobs that take minutes or hours to complete. Spark has designed to run on top of Hadoop and it is an alternative to the traditional batch map/reduce model that can be used for real-time stream data processing and fast interactive queries that finish within seconds. So, Hadoop supports both traditional map/reduce and Spark.
We should look at Hadoop as a general purpose Framework that supports multiple models and we should look at Spark as an alternative to Hadoop MapReduce rather than a replacement to Hadoop.
3. Hadoop MapReduce vs. Spark: Which One to Choose?
Spark uses more RAM instead of network and disk I/O its relatively fast as compared to hadoop. But as it uses large RAM it needs a dedicated high end physical machine for producing effective results.
It all depends and the variables on which this decision depends keep on changing dynamically with time.
