Description

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.
