Description
Hive support different versions of hadoop such as 0.20,0.20S(1.0.0) and 0.23.0(2.0.1). When we build hive with hadoop-0.23(2.0.1), we get compilation error in eclipse because it is refering to 0.20.0 hadoop jars.
Currently, hive classpath is generated with pre-defined eclipse template.This template support only for 0.20 version of hadoop. This is causing compilation error in eclipse.

I do not think we want to version them unless we really have to.
As it stands now the eclipse templates are already confusing so they can not get much worse.
I have 2 approached to handle this problem.
1. Maitain differnt eclipse template for different version of hadoop.
2. Make current eclipse template as generic such a way that all the tokens in the template is replaced with value.
I suggest for first approach because different hadoop version require differnt version of dependent jar.
For example hadooop-0.20 require common-codec-1.3.jar where hadoop-0.23.0 require common-codec-1.4.jar.
