Ahmed Fathalla commented on CHUKWA-4:
-------------------------------------

I am working on a patch to solve this bug, however i am unsure if we need to change code in
CollectorStub or ServletCollector classes? Does anyone have any guidance about what should
be done to implement changes suggested in previous comments?

> When I use start-collectors, it creates the datasink as expected, writes to it as per
normal, i.e. writes to the .chukwa file, and roll overs work fine when it renames the .chukwa
file to .done. However, when I use bin/stop-collectors to shut down the running collector
it leaves a .chukwa file in the HDFS file system. Not sure if this is a valid sink or not,
but I think that the collector should gracefully clean up the datasink and rename it .done
before exiting.
