Could someone give me a list of the basic Java classes that are needed
to run a program in Hadoop?  By basic classes I mean classes like Mapper
and Reducer that are essential in running programs in Hadoop.  

 

Thanks,

Mapper, Reducer, Configuration, Job / JobConf and Tool. All pretty
essential. Plus InputFormats and OutputFormats, FileSystem and Path. Don't
forget Partitioners and Comparators.

Hope that helps!
