----------------------------------------------
Summary: Improve logging around HTTP connections
Key: IMPALA-9987
URL: https://issues.apache.org/jira/browse/IMPALA-9987
Project: IMPALA
Issue Type: Task
Components: Backend
Affects Versions: Impala 4.0
Reporter: Thomas Tauber-Marshall
Assignee: Thomas Tauber-Marshall
The existing logging around HTTP connections is poor. Some improvements that
could be made:
- There are several messages that are logged on every connection creation and
disconnect, sometimes resulting in large amounts of un-informative log spam.
These could be moved to a higher vlog level.
- More vlog-ing in general could be added to help in debugging issues.
- The frequent "auth failed" message that gets logged in the
not-actually-an-error situation that a client doesn't send an auth header on
its first connection attempt until it sees the WWW-Authenticate can be
misleading.
