Description

We currently write a dummy impala hive serde classname in the metastore for parquet. "com.cloudera.impala...ParquetInputOutFormat". This needs to be updated to use the path in the parquet-mr project when that is released and probably updated again if the serde makes it into hive proper.

We'll need to continue to allow reading tables with older class strings for compatibility but should set the metadata with the "most proper" class.
