Big Data Analytics for Non-Programmers презентация

If you want to write MapReduce program, then you can use Pig and Pig Latin for which knowledge of Java is not required.

If you want to view data in HDFS in a readable form you can use Hive which again does not require any knowledge of Java.

Additionally, If you want to write your own MapReduce code, you can do so in any language (e.g. Perl, Python, Ruby, C, etc.)

But the most attractive features of Pig are:

10 lines of PIG = 200 lines of Java

Built in operations like:

Join
Group
Filter
Sort
and more…

It is Open source and is actively supported by a community of developers.
