The normal committer relies on directory rename() being atomic for > this; for S3 we don't have that luxury. > To support a custom committer, we need to be able to tell FileOutputFormat > (and implicitly, all subclasses which don't have their own custom committer), > to use our new {{S3AOutputCommitter}}. > I propose: > # {{FileOutputFormat}} takes a factory to create committers. > # The factory to take a URI and {{TaskAttemptContext}} and return a committer > # the default implementation always returns a {{FileOutputCommitter}} > # A configuration option allows a new factory to be named > # An {{S3AOutputCommitterFactory}} to return a {{FileOutputCommitter}} or > new {{S3AOutputCommitter}} depending upon the URI of the destination. > Note that MRv1 already supports configurable committers; this is only the V2 > API -- This message was sent by Atlassian JIRA (v6.4.14#64029) --------------------------------------------------------------------- To unsubscribe, e-mail: mapreduce-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: mapreduce-issues-h...@hadoop.apache.org
