----------------------------------------------------------------
I've rebuilt everything with mvn clean package and redeployed just in case and
things still aren't changing. I can run it and not shutdown, and it will just
stay inactive after it hits Creating instance of filechannel. I'm going to try
and add some extra traces and take a stack dump, and I'll get back to this
hopefully with some more useful info as it doesn't look like you can recreate
it. I'm guessing it's some issue with our setup and that the necessary error
messages aren't being generated.
Premature incorrect assumption on that last edit sorry, going to take the time
to just trawl this thoroughly and then get back once I've fixed it
was (Author: juhanic):

edit: Turns out that my new problem is with mvn clean package not actually
putting the file channel into the tar binary for distribution(even though mvn
is giving a success: [INFO] Flume NG file-based channel .......................
SUCCESS [2.901s]), and also with the FlumeException that should be reporting
the missing class getting swallowed up, 2 separate new issues I guess.

> Project: Flume
> Issue Type: Bug
> Components: Channel
> Affects Versions: v1.2.0
> Environment: CentOS 5.4
> Reporter: Juhani Connolly
> Attachments: flume-hari-2012May312217PST.log, flume.log, flume.log,

> 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
