Review Comment:
HbaseSerDe unlike Avroserde is not configured to adopt to external schema
changes. If the schema evolves in HBase, the getFieldsFromDeserializer() method
in Hive still returns schema from metastore SD . So, schema is always derived
from 'hbase.column.mappings' property in metastore. In case of AvroSerDe, Hive
reads the live schema from external url. So, it seems safe to have HbaseSerDe
in Metastore Schema config list.
