Sean Hsuan-Yi Chu updated DRILL-1786:
-------------------------------------
Component/s: Execution - Flow
> Query "Show Tables" runs through all storage plugins even if a schema is
> specified
> ----------------------------------------------------------------------------------

> Key: DRILL-1786
> URL: https://issues.apache.org/jira/browse/DRILL-1786
> Project: Apache Drill
> Issue Type: Improvement
> Components: Execution - Flow
> Reporter: Sean Hsuan-Yi Chu
> Assignee: Sean Hsuan-Yi Chu
>
> After a schema is chosen, we can query the table list in the specified schema
> by "show tables".
> However, I noticed the method "getTableNames()" in every storage-plugin is
> called through the life-cycle of this query. This seems not necessary.
> Especially, when you have an unresponsive data source (DRILL-1343), the query
> result would not be returned even if you type "show tables" under a healthy
> data source
