> Web interface hangs after query-submission error

> Key: DRILL-2104
> URL: https://issues.apache.org/jira/browse/DRILL-2104
> Project: Apache Drill
> Issue Type: Bug
> Components: Client - HTTP
> Reporter: Daniel Barclay (Drill)

> Fix For: 1.2.0

> On the query page, getting an error seems to jam up the web application.
> Example 1:
> 1. Go to query page.
> 2. Click on Submit button (with empty query, type defaulted to "SQL").
> 3. (Get "HTTP ERROR 500 \n Problem accessing /query. Reason: \n Request
> failed." error.)
> 4. Click on browser Back button.
> 5. (Get query page.)
> 6. Click on Submit button.
> 7. Web application hangs--browser indicates it's waiting. (In current case,
> Mozilla SeaMonkey says "Waiting for localhost..." and "Stop" icon is enabled.)
> Example 2:
> 1. Go to query page.
> 2. Copy sample query ("SELECT * FROM cp.`employee.json` LIMIT 20") and paste
> into query box.
> 3. Click Submit button.
> 4. (Get tabular results page.)
> 5. Click on browser Back button.
> 6. (Get query page, with query still there.)
> 7. Edit query, adding apparent syntax error (e.g., append ";" to end).
> 8. Click Submit button.
> 9. (Get "HTTP ERROR 500" page (rather than good "syntax error" message).)
> 10. Click on browser Back button.
> 11. (Get query page, with (bad) query still there.)
> 12. Fix query (e.g., remove bad appended ";" from end).
> 13. Click Submit button.
> 14. Web application hangs--browser indicates it's waiting.
