--------------------------------------
Summary: FileSystemPlugin refactoring: avoid sharing
DrillFileSystem across schemas
Key: DRILL-2413
URL: https://issues.apache.org/jira/browse/DRILL-2413
Project: Apache Drill
Issue Type: Sub-task
Components: Metadata, Storage - Information Schema
Reporter: Venki Korukanti
Assignee: Venki Korukanti
Fix For: 0.9.0
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.
