> Key: DRILL-6760
> URL: https://issues.apache.org/jira/browse/DRILL-6760
> Project: Apache Drill
> Issue Type: Bug
> Components: Web Server
> Affects Versions: 1.14.0
> Reporter: Nitin Sharma
> Assignee: shuifeng lu
> Priority: Major
> Labels: ready-to-commit
> Fix For: 1.15.0
>
>
> The profiles page (that shows query execution for the most recently issued
> queries) on the foreman node does not retain the original exception if the
> query failed. The error always says "Remote Drill Exception" and gives an id.
> The actual exception could be anything from OOM, s3 access errors, out of
> disk issue etc but they seem to get swallowed.
>
> It is hard to debug if there are long running queries.
