6.4 Comparison of Pig, Hive and MapReduce
Writing MapReduce programs require Java skills and you need to write so many lines of plain JAVA code.
Pig Latin and Hive SQL sits on one layer up of Hadoop ecosystem and provides high level language for using Hadoop's MapReduce library.
With Pig Latin and Hive SQL you can write your map-reduce programs without using Java at all.
Pig scripts takes 5% of the time compared to writing MapReduce programs in Java but run time performance reduce by 50% due to obvious reason that MapReduce programs (in Java) runs natively.
Pig Latin is script language and at the moment, there is no IDE or text editor that can provide help or intelligence in maintaining Pig code .
There is a lot of overhead in loading Pig platform, preparing it to pre-process and run the script.
