Grant Henke updated KAFKA-2999:
-------------------------------
Status: Patch Available (was: Open)
> Errors enum should be a 1 to 1 mapping of error codes and exceptions
> --------------------------------------------------------------------
>
> Key: KAFKA-2999
> URL: https://issues.apache.org/jira/browse/KAFKA-2999
> Project: Kafka
> Issue Type: Bug
> Affects Versions: 0.9.0.0
> Reporter: Grant Henke
> Assignee: Grant Henke
>
> Errors has functionality to map from code to exception and from exception to
> code. This requires the mapping to be 1 to 1 or else unexpected behavior may
> occur.
> In the current code (below), a generic ApiException will result in an
> INVALID_COMMIT_OFFSET_SIZE error, because that is the last occurrence in the
> Enum.
> {code:title=Error.java|borderStyle=solid}
> ...
> for (Errors error : Errors.values()) {
> codeToError.put(error.code(), error);
> if (error.exception != null)
> classToError.put(error.exception.getClass(), error);
> }
> ...
> {code}
> This should be fixed and some tests should be written to validate it's not
> broken.
