# [DRILL-8121](https://issues.apache.org/jira/browse/DRILL-8121): Add
UserSession to StoragePlugins
## Description
One of the major limitations of Drill is that per-user credentials are not
supported in non-Hadoop, or file system storage plugins. In conducting
experiments, one of the major challenges preventing this was that there was no
reliable way for a storage plugin to obtain the username of the user who
submitted the query.
This PR represents the first step in making this possible by passing the
UserSession object down to the storage plugin instance. Thus for each query,
the storage plugin can obtain the active user id. This does not affect any
current Drill behavior, but will make it possible to implement per-user
credentials for plugins such as JDBC, Splunk, ElasticSearch and others that do
not have the concept of user impersonation.
## Documentation
No user facing changes
## Testing
Added unit tests.
