Vinod Kumar Vavilapalli commented on YARN-888:
----------------------------------------------

Makes sense now. I think I understand the main trouble point. I think this is 
the one:
{quote} unless you only put in non-leaf POMs dependencies that are common to 
all the leaf modules. {quote}
Today we put any dependency needed by *any* leaf-module in the non-leaf module. 
That clearly adds a lot of burden on leafs that don't need those libs. Am I 
understanding that correctly? If so, yeah, let's go for it. At the end of the 
day, the deps that user sees needs to be as clean as possible.

> Intermediate 'pom' modules define dependencies inherited by leaf modules.
> This is causing issues in intellij IDE.
> We should normalize the leaf modules like in common, hdfs and tools where all 
> dependencies are defined in each leaf module and the intermediate 'pom' 
> module do not define any dependency.
