Hello All, I have developed a simple compiler that compiles object specifications into Hadoop Writable and WritableComparable objects. The purpose of this is to avoid writing boilerplate code every time you need to have a custom data type passed around in Hadoop. As input it takes a specification containing a list of objects and their fields and generates Java classes that implement Hadoop's Writable or WritableComparable and can serialize and de-serialize these fields. This compiler is still in its very early stages but I have found it useful throughout my work with different Hadoop based projects. I would appreciate any feedback on this!
The project (download, wiki, and source code) is here: http://code.google.com/p/hadoop-data-adapters/ Thank you, - Slava Chernyak
