Hive settings are not passed to Orc/Avro SerDes, when used from HCatalog

We find that tables/partitions accessed through HCatLoader/HCatStorer use Hive settings hard-coded in HiveConf, rather than settings in the hive-site.xml. For instance, ORC files written through Pig/HCatStorer use default orc.stripe.size settings, rather than any overrides in hive-site.xml.

This has to do with the way the HiveStorageHandler is constructed in the HCat path. I'll upload the fix shortly.
