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
