------------------------------------
Summary: StreamsGroupDescribe does not return tasks pending
revocation
Key: KAFKA-21182
URL: https://issues.apache.org/jira/browse/KAFKA-21182
Project: Kafka
Issue Type: Bug
Reporter: sanghyeok An
Assignee: sanghyeok An
The Assignment field in StreamsGroupDescribe currently includes only
assignedTasks, excluding tasks in tasksPendingRevocation. However, the
coordinator still considers the member responsible for these tasks until
revocation is acknowledged.
When an active task moves from member A to member B, it can therefore disappear
from both members’ current assignments in the Describe response: A is still
pending revocation, while B cannot receive the task until A releases it. This
makes it difficult to identify which member is holding up the transfer.
The same issue was fixed for consumer groups in KAFKA-20431. We should
similarly include tasks pending revocation in the assignment returned by
StreamsGroupDescribe, covering active, standby, and warm-up tasks.
