# [DRILL-7630](https://issues.apache.org/jira/browse/DRILL-7630): Add
additional types into SchemaParser for Parquet
## Description
Parquet files supports some types that are currently not included in the
schema parser. Since schema parser is used during schema ser / de, processing
of such Parquet files fails. We need to add additional data types to the schema
parser.
## Documentation
NA
## Testing
Added unit test, ran all tests.

> Drill uses SchemaParser when deserializing schema in a group scan. Also, it
> is used when deserializing schema from the metastore.
> The aim of this Jira is to add some absent types to fix issues when these
> types are used in the data file.
> Example of the failing test:
> {code:java}
> PlanTestBase.testPhysicalPlanExecutionBasedOnQuery("select * from
> cp.`parquet/uint_types.parquet`");
> {code}
> List of types to add:
> {code}
> MinorType.UINT1;
> MinorType.UINT2;
> MinorType.UINT4;
> MinorType.UINT8;
> MinorType.TINYINT;
> MinorType.SMALLINT;
