Subject [jira] [Created] (DRILL-1786) Query "Show Tables" runs through all storage plugins even if a schema is specified

----------------------------------------

             Summary: 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
            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
