------------------------------------

Hi  Vikram,

Thanks for taking a look at this!  What we do is:

1) Build each shim with it's specific version of hadoop
2) Package them all together in a single jar via shims/assembly/*

That way all the hive projects only have to depend on the single bundled 
hive-shims jar which contains all the shims for all versions of hadoop. Then at 
runtime we use the version of hadoop which is available to decide which shim to 
load.
