Aroop Maliakkal commented on HIVE-17115:
----------------------------------------
[~daijy] :: The create tables succeeded. We might be using the direct mysql
connection from the hive client when we were creating these tables. Now we
enforced all clients to go through metastore instead of direct mysql connection.
> MetaStoreUtils.getDeserializer doesn't catch the
> java.lang.ClassNotFoundException
