----------------------------------------
Summary: Original exception gets masked by later exception
Key: ASTERIXDB-3472
URL: https://issues.apache.org/jira/browse/ASTERIXDB-3472
Project: Apache AsterixDB
Issue Type: Bug
Components: HYR - Hyracks
Reporter: Ali Alsuliman
Assignee: Ali Alsuliman
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.
