Subject Re: Flume custom source stopping after some time when started through java program.
Date Mon, 14 Jul 2014 10:34:43 GMT
Hi sarvana,

My flume agent is surely running, when I see in running processes ps -ef it
is showing flume agent process is running.But my custom source is not
I have implemented logging, if flume custom source is running then it will
write to log files. I have written many log statements I know where it is
stopping, but not know why it is stopping.

My custom source works fine as when I run from shell directly but not from
java program, then custom source is running for many hours.
And also flume is working fine I have written other custom sources before
and they are running for days continuously when I start from java program.
Here I'm not understanding what is happening internally, when I start to
run flume through java program then only my custom source stops working
where as when I run through shell then it is working fine. Is your case is
also similar.

How are you starting flume, either by java program or by shell?
