### Problem Description 1. TransactionBufferHandlerImpl sends EndTxn request, at this time topic is unloading. 2. The default timeout is 3 seconds, and a timeout exception will be returned after three seconds. 3. The response is received later, but the op has been removed by timeout. ```java 2022-01-20T14:17:54,167+0800 [pulsar-io-30-3] DEBUG org.apache.pulsar.broker.transaction.buffer.impl.TransactionBufferHandlerImpl - Got end txn on topic response for timeout 14 - 3006 ``` 4. TransactionMetadataStoreService receives RequestTimeoutException, which is a retry exception, so TC will use transactionOpRetryTimer to try again. But at the same time this RequestTimeoutException will be returned. ### Solution Use the same CompletelyFuture to retry without returning a timeout exception https://github.com/apache/pulsar/pull/13828 -- This is an automated message from the Apache Git Service.
