# [DRILL-8279](https://issues.apache.org/jira/browse/DRILL-8279): Use thick
Phoenix driver
## Description
`phoenix-queryserver-client` shades Avatica classes, so it causes issues
when starting Drill and shaded class from phoenix jars is loaded before
official Avatica, so Drill wouldn't be able to start correctly.
- Fixed Phoenix unit tests to run with general tests suite without any extra
checks
- Added support for Phoenix thick client
- Removed usage of custom dependencies
## Documentation
To use fat client, storage plugin configs should be updated as described in
https://github.com/apache/drill/compare/master...vvysotskyi:DRILL-8279?expand=1#diff-81178bb7d4498bc22f7c54e71462b460f95b80f40f85e74ff8f1cc7f69d34351
## Testing
All unit tests pass, queried Phoenix using Drill.
