Zhangyx39 opened a new pull request #1435:
URL: https://github.com/apache/samza/pull/1435
Symptom: String.format("..." + key) would through
MissingFormatArgumentException if the key string contains something like "%3A"
or "%d". And original exception would be hidden by this new exception.
Cause: We have no control on what the key can be. Should avoid using
String.format().
Changes: Simply remove the String.format() should be enough.
Tests: No test since it's a minor change.
API Changes: No API change.
Upgrade Instructions: No backward-compatibility issue. No need to upgrade.
Usage Instructions: User won't use this code directly.
