-----------------------------------
Summary: Umbrella Issue to Improve Error Messages to Users in
Apache Drill
Key: DRILL-5692
URL: https://issues.apache.org/jira/browse/DRILL-5692
Project: Apache Drill
Issue Type: Task
Components: Server, Documentation, Execution - Flow, Execution -
Monitoring
Reporter: John Omernik
This is a master JIRA to link to other specific examples of unhelpful error
messages in Drill. There are a number of error messages built into Drill that
when provided to a user, even with ALTER SESSION SET `exec.errors.verbose` =
true, provides little for the user to go on to troubleshoot there message.
While messages have been improving, having a master JIRA to track these
individual errors will help improve the product as a whole. To that end, when
creating a new JIRA to be linked to this one with a specific error message,
please include the following information.
1. The Error Message
2. The Verbose Error message ( Run the query: ALTER SESSION SET
`exec.errors.verbose` = true; then run the query or perform the action that
caused the message)
3. The storage plugin used. (Filesystem, MongoDB, Hbase, etc)
4. The File types being queried (If using filesystem storage plugin) For
example: CSV, JSON, Parquet etc.
5. The context for the error message, i.e. it happens all the time, it happens
some of the time, randomly, only when the moon traverses the constellation
Scorpio... etc.
6. If you were able to resolve the issue, what was the cause? This will be
helpful and providing "tips" to the users if possible.
7. Did you find any documentation related to this error in the Drill
Documentation Pages?
8. What information would be more helpful for you?
9. ????
10. Profit.
11. Also link to this issue in your issue so we know it's linked to bigger
improvement of Drill error messages.
Once you create the individual issue, post a comment here with a link to your
new issue. The idea is we have a single point to understand all the
frustrating error messages we can make real progress on the larger issue of
error messages with in Drill!
