> URL: https://issues.apache.org/jira/browse/IMPALA-5872
> Project: IMPALA
> Issue Type: Improvement
> Components: Frontend
> Reporter: bharath v
> Assignee: bharath v
> Priority: Major
> Labels: supportability
> Fix For: Impala 3.2.0
>
>
> The idea is to implement a test case builder for collecting enough
> diagnostics for a given SQL query so that it can be reproduced/recreated on
> another cluster easily.
> Input: A valid SQL query
> Expected output: A .sql file that can be run using {{impala-shell -f}} and
> has all the schema/table/view definitions required to run the query on a
> target cluster.
> An example:
> {noformat}
> EXPORT TESTCASE INTO OUTFILE 'file:///tmp/repro.sql' select * from view
> {noformat}
