> Hive was having a newer version of httpclient and httpcore since 1.2.0 (HIVE-9709), when
compared to Hadoop 2.x versions, to be able to make use of newer apis in httpclient 4.4.
> There was  security issue in the older version of httpclient and httpcore that hadoop
was using, and as a result moved to httpclient  4.5.2  and httpcore 4.4.4 (HADOOP-12767).
> As hadoop was using the older version of these libraries and they often end up earlier
in the classpath, we have had bunch of difficulties in different environments with class/method
not found errors. 
> Now, that hadoops dependencies in versions with security fix are newer and have the API
that hive needs, we can be on the same version. For older versions of hadoop this version
update doesn't matter as the difference is already there.
