----------------------------------
Summary: Metrics for tracking query failure reasons
Key: IMPALA-8714
URL: https://issues.apache.org/jira/browse/IMPALA-8714
Project: IMPALA
Issue Type: Improvement
Components: Backend
Affects Versions: Impala 3.3.0
Reporter: Michael Ho
A query can fail for various reasons when run in Impala:
- analysis failure (e.g. SQL syntax mistake)
- access right issue (e.g. no privilege for certain ops on a table)
- memory limit exceeded
- executor crashes
- rpc failures
- corrupted data files
This JIRA tracks the effort to explicitly classify query failures into some
high level categories and expose them in the metrics. This should provide us a
clearer view of what types of failures contribute the most to bad user
experience for a given cluster.
