Description

Here is my config for flume.
agent: : rpcSource(333)| agentDFOChain("192.168.130.15:17876","192.168.130.14:17876")
collector: collector(17876)|myCustomplugin

Here is my test case:

1. use an rpcClient send one event to agent every munite.
2. shutdown the primay collector and sendory collector
3. wait about 1.5h, start the sendory collector

In my expect, the events received by agent at the posted time of the secondary recovered, should be send to sendory collector, but in actually, the events just be discard as it be send to the null sink in BEChain.

Here is my log:[2012-01-20 10:19:00,098] [INFO ] [logicalNode ESC01_agent-24] [com.cloudera.flume.handlers.debug.StubbornAppendSink 76] Append failed java.net.SocketException: No route to host
