BUG-37910 hive hook defines its own hadoop version instead of using parents and can cause run time issues

bad dependency on calcite-0.9.2-incubating-snapshot which is no longer
useable and Hive POM needs to be updated at Central for Hive 0.14 and
Hive 1.0 to make it calcite-0.9.2-incubating. Removed where/groupby
parsing for now as value is limited and doesnt parse nested queries
well.  Handle createtable/createview and prepare to handle alters and
inserts

Adds Apache License Headers, enables rat-check, find-bugs and checkstyle plugins. Contributed by Venkatesh Seetharam
