Sijie Guo commented on BOOKKEEPER-69:
-------------------------------------
A proposal to fix this issue is:
1) make sure only one acquireOp is executed when acquiring a topic in topic
manager.
2) the other requests to the under-acquisition topic, will queue their
callbacks.
3) when the topic acquisition is done, all the queued callbacks will be
triggered according to the acquisition result.
> ServerRedirectLoopException when a machine (hosts bookie server & hub server)
> reboot, which is caused by race condition of topic manager

> Key: BOOKKEEPER-69
> URL: https://issues.apache.org/jira/browse/BOOKKEEPER-69
> Project: Bookkeeper
> Issue Type: Bug
> Components: hedwig-client, hedwig-server
> Affects Versions: 3.4.0
> Environment: 3 machines (perf8, perf9, perf10), each machine hosts a
> bookie server & a hub server.
> perf8 is used as default server for client 1. perf9 is used as default server
> for client 2.
> bookkeeper is configured as below:
> ensemble size is 3, quorum size is 2.
> Reporter: Sijie Guo
> Priority: Critical
>
> 1) machine perf10 is rebooted. the bookie server & hub server are not
> restarted automatically after reboot.
> 2) client 1 & client 2 are still running. the topics owned in perf10 will be
> re-assigned to perf8/perf9. but they would fail because not enough bookie
> servers are available.
> 3) after 2 hours, we found that perf10 is rebooted. we restarted bookie
> server & hub server on perf10
> 4) then we got ServerRedirectLoopException in client.
