Subject [jira] Commented: (CHUKWA-338) duplicate suppression in archiver
Date Mon, 13 Jul 2009 20:35:14 GMT

    [ https://issues.apache.org/jira/browse/CHUKWA-338?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12730501#action_12730501

Jerome Boulon commented on CHUKWA-338:
--------------------------------------

The ChukwaArchiveKey contains a TimePartition so you may not removed all duplicates (outside
of the 1 hour TimePartition window) and this will also be true in case of backfilling.
Is that a problem for you?

> Right now, Archiver uses an identity reducer.
> It should be straightforward to write a custom reducer that does duplicate detection
and suppression if we get multiple chunks with the same key.
