> Reporter: Ali Alsuliman
> Assignee: Ali Alsuliman
> Priority: Major
> Labels: triaged
>
> When executing the tasks of a query and a failure happens in a task, the
> original exception can get masked by a later exception leading to the loss of
> the root cause of the query failure. As an example, when a task encounters a
> failure during opening its pipeline, the pipeline will be closed as usual
> (and the failure should be reported). However, if another failure happens
> during closing the pipeline, this later exception masks the original
> exception. There is no way to debug such cases any further since the root
> cause is gone.
