Question

我现在已经使用了一段时间了，我已经在同一台机器上运行了代理和收集器。

配置

agent: exec("/usr/bin/tail -n +0 -F /path/to/file") | agentE2ESink("hostname", 35855)
collector: collectorSource(35855) | collector(10000) { collectorSink("/hdfs/path/to/sink","name") }

面对代理节点中的问题：

2012-06-04 19:13:33,625 [naive file wal consumer-27] INFO debug.InsistentOpenDecorator: open attempt 0 failed, backoff (1000ms): Failed to open thrift event sink to hostname:35855 : java.net.ConnectException: Connection refused
2012-06-04 19:13:34,625 [logicalNode hostname-19] ERROR connector.DirectDriver: Expected ACTIVE but timed out in state OPENING
2012-06-04 19:13:34,632 [naive file wal consumer-27] INFO debug.InsistentOpenDecorator: open attempt 1 failed, backoff (2000ms): Failed to open thrift event sink to hostname:35855 : java.net.ConnectException: Connection refused
2012-06-04 19:13:36,635 [naive file wal consumer-27] INFO debug.InsistentOpenDecorator: open attempt 2 failed, backoff (4000ms): Failed to open thrift event sink to hostname:35855 : java.net.ConnectException: Connection refused

然后将连续发送空ACK

2012-06-04 19:19:56,960 [Roll-TriggerThread-0] INFO endtoend.AckListener$Empty: Empty Ack Listener began 20120604-191956958+0530.881565921235084.00000026
2012-06-04 19:20:07,043 [Roll-TriggerThread-0] INFO hdfs.SeqfileEventSink: closed /tmp/flume-user1/agent/hostname/writing/20120604-191956958+0530.881565921235084.00000026

我不明白为什么拒绝连接。是否需要进行任何系统级别的更改？

注意：收集器正在侦听端口，但代理无法通过35855端口发送数据。

任何人都可以帮我解决这个问题。

如果您在同一个盒子上同时运行代理和收集器，则应使用localhost作为地址。

agentE2ESink("localhost", 35855)

Flume代理抛出java.net.ConnectException：连接被拒绝
