Would you please also point out that what kind of scenario will this issue
be reproduced?
> The config `syncFlushTimeout` doesn't work for SYNC_MASTER
> ----------------------------------------------------------
>
> Key: ROCKETMQ-272
> URL: https://issues.apache.org/jira/browse/ROCKETMQ-272
> Project: Apache RocketMQ
> Issue Type: Bug
> Components: rocketmq-broker
> Affects Versions: 4.1.0-incubating
> Reporter: Yu Kaiyuan
> Assignee: yukon
>
> It's quite frequent to get result as `sendStatus=FLUSH_SLAVE_TIMEOUT` when
> sending big messages(>500k) in SYNC_MASTER/SLAVE scenario.
> The timeout value used by the sync process currently as I found, is the
> config `syncFlushTimeout`. And its default value is 5000 milliseconds.
> But it shows that producer get the result as `FLUSH_SLAVE_TIMEOUT` less than
> 1 second.
> So why does the config not work as expected?
> Relevant code:
> {code:java}
> // CommitLog.java
> public void handleHA(AppendMessageResult result, PutMessageResult
> putMessageResult, MessageExt messageExt) {
> if (BrokerRole.SYNC_MASTER ==
> this.defaultMessageStore.getMessageStoreConfig().getBrokerRole()) {
> HAService service = this.defaultMessageStore.getHaService();
> if (messageExt.isWaitStoreMsgOK()) {
> // Determine whether to wait
> if (service.isSlaveOK(result.getWroteOffset() +
> result.getWroteBytes())) {
> GroupCommitRequest request = new
> GroupCommitRequest(result.getWroteOffset() + result.getWroteBytes());
> service.putRequest(request);
> service.getWaitNotifyObject().wakeupAll();
> boolean flushOK =
>
> request.waitForFlush(this.defaultMessageStore.getMessageStoreConfig().getSyncFlushTimeout());
> if (!flushOK) {
> log.error("do sync transfer other node, wait return, but
> failed, topic: " + messageExt.getTopic() + " tags: "
> + messageExt.getTags() + " client address: " +
> messageExt.getBornHostNameString());
>
> putMessageResult.setPutMessageStatus(PutMessageStatus.FLUSH_SLAVE_TIMEOUT);
> }
> }
> // Slave problem
> else {
> // Tell the producer, slave not available
>
> putMessageResult.setPutMessageStatus(PutMessageStatus.SLAVE_NOT_AVAILABLE);
> }
> }
> }
> }
> {code}
