    FileChannels Event implementation uses Hadoop IO's Writable for serialization. Without it a class loader error is thrown but never caught and logged killing the thread invisibly. This repeats and puts flume into a state where interrupts are not responded to, making clean shutdown impossible old desc for posterity: Reduced to a minimal configuration for simplicity. I can recreate this on some machines, and not others. I wouldn't be surprised if it is some machines specific issue(test machines on CentOS5.4. On some it worked, others not), however whatever exception was thrown when attempting to get created is consumed and never passed onwards Config: test.channels.ch1.type = file test.channels.ch1.checkpointDir = /home/share/juhani_connolly/flume-1.2.0-incubating-SNAPSHOT/check test.channels.ch1.dataDirs = /home/share/juhani_connolly/flume-1.2.0-incubating-SNAPSHOT/filechdata test.sources.top.type = exec test.sources.top.command = /usr/bin top -b -d 1 test.sources.top.restart = true test.sources.top.restartThrottle = 1000 test.sources.top.interceptors = ts test.sources.top.interceptors.ts.type = org.apache.flume.interceptor.TimestampInterceptor$Builder test.sources.top.channels = ch1 test.sinks.log.type = logger test.sinks.log.channel = ch1 test.channels = ch1 test.sources = top test.sinks = log attaching logs with general/lifecycle loglevel down to debug. A solution to this is probably going to be just improving error reporting. Another possibly more important element is that flume enters a state from which it cannot shutdown without kill -9. It looks like the Interrupts are getting swallowed up silently somewhere
