Subject [jira] Commented: (CHUKWA-4) Collectors don't finish writing .done datasink from last .chukwa datasink when stopped using bin/stop-collectors
Date Sun, 28 Mar 2010 05:10:27 GMT

    [ https://issues.apache.org/jira/browse/CHUKWA-4?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12850636#action_12850636

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

if we are using the same prefix for the recovering part and if collector is killed while writing
to the SeqFile then you will no longer be able to identify the initial SeqFile. You'll have
2 .chukwa file, one will be an unclosed File, the other will be the one you were recovering
into.
Having a specific .recover extension will solve that problem since you can ignored it at re-start
time.

> 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.
