> Currently we create one DrillFileSystem (an extension of hadoop FileSystem)
> instance and share it across all Workspaces created for all queries,
> FormatPlugins and FormatMatcher. Remove the shared DrillFileSystem instead
> share the DrillFileSystem configuration and create a DrillFileSystem in each
> Schema (WorkspaceSchema) using the current user credentials in Schema. The
> same DrillFileSystem instances to passed to FormatPlugins and FormatMatchers
> whenever Schemas need to access the file system.
