 Tables using random distribution are preferred for registering into HAWQ. If hash tables are to be  registered, the distribution policy in the YAML file must match that of the table being registered into.

 Metadata for the Parquet file(s) and the destination table must be consistent. Different  data types are used by HAWQ tables and Parquet files, so the data is mapped. Refer to the section [Data Type Mapping](hawqregister.html#topic1__section7) below. You must verify that the structure of the Parquet files and the HAWQ table are compatible before running `hawq register`.
