NiXuebing commented on issue #206: FLUME-2956 - hive sink not sending heartbeat correctly URL: https://github.com/apache/flume/pull/206#issuecomment-465391257 我看HiveSink.java里`setupHeartBeatTimer()`的作用也仅仅是将`timeToSendHeartBeat`设置为`true`，实际触发心跳还是得等消息来时的flush。如果长时间没有消息，事务还是会自动断开。 我的处理是`HiveSink.setupHeartBeatTimer()`里直接加上`writer.heartBeat()`，不知道这样有没有问题
