Subject [jira] Commented: (CHUKWA-4) Collectors don't finish writing .done datasink from last .chukwa datasink when stopped using bin/stop-collectors

    [ https://issues.apache.org/jira/browse/CHUKWA-4?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12850206#action_12850206

Jerome Boulon commented on CHUKWA-4:
------------------------------------

This is because HDFS is closing the fileSystem on kill -term (shutdownHook).
The workaround is to remove the HDFS shurdown hook and call it after the collector close but
it's just a workaround.

> 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.
