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