Major Description
Now for branch-2.x, we will build with hadoop 3.x in the hadoop check stage, so in later unit check, if we run from a sub module, then the other hbase modules we depend on will depend on hadoop 3.x while the module we build will depend on 2.x, this will cause the following problem
