sert data into those types of tables. Similarly, with the Avro file type, Impala heavily
depends on Hive to provide additional support to process such data formats.
If you have a file format that you know is not supported by Impala, you can first create

shell or through an API. After that, you can query the same Hive table in Impala.
Tip
With the arrival of Impala 1.2, support for various file and compression formats
could change, so it is recommended that you please visit Cloudera Impala docu-
mentation for additional file type and compression support information.
