[jira] [Created] (METRON-732) When an error happens in an composed
function in stellar, the real exception is not bubbled up
Casey Stella created METRON-732:
-----------------------------------
Summary: When an error happens in an composed function in stellar, the real exception is not bubbled up
Key: METRON-732
URL: https://issues.apache.org/jira/browse/METRON-732
Project: Metron
Issue Type: Bug
Reporter: Casey Stella
If you have a function which throws an exception and it is an inner function of a composition, then the exception isn't bubbled up.
For instance, if {{PROFILE_WINDOW}} throws an exception in the following:
{{STATS_MEAN(STATS_MERGE(PROFILE_GET('stat', 'global', PROFILE_WINDOW('5 minute window starting ago'))))}}
We will get
{{org.apache.metron.common.dsl.ParseException: Unable to execute: expected at least 3 argument(s), found 2}}
Rather than the actual exception thrown from PROFILE_WINDOW
