Invalidate metadata before loading parquet data through Impala.
Invalidate metadata before loading parquet data through Impala.

During a full data load, we load all the data (except parquet) via hive, and then load the
parquet data via Impala. The catalog service does not update the metadata of tables
changed outside Impala, so we need to explicitly invalidate the metadata before loading
parquet data.
