Hadoop

An open-source software framework for distributed storage of very large data sets on computer clusters. Scale your data up and down without worrying about hardware failures.Hadoop provides massive amounts of storage for any kind of data, enormous processing power and the ability to handle virtually limitless concurrent tasks or jobs.

Hadoop provides massive amounts of storage for any type of data, enormous processing power and the ability to handle virtually limitless concurrent tasks or jobs.

Not for the data beginner. To harness its power, you need to know Java.Many other companies and technologies run off of it or integrate with it.

Many companies use it, many technologies rely on and many more integrate with it, so it may be worth learning Java.

Spark (Apache)

A fast and general engine for large-scale data processing which easily integrates with pplications written in Java, Scala, Python and R.

Spark can run on Hadoop, Mesos or standalone accessing diverse data sources such as HDFS, Cassandra, HBase, and S3.

Run applications up to 100x faster than Hadoop MapReduce in memory, or 10x faster on disk
