> Key: FLUME-640
> URL: https://issues.apache.org/jira/browse/FLUME-640
> Project: Flume
> Issue Type: Improvement
> Affects Versions: v0.9.3
> Reporter: Disabled imported user
> Labels: acknowledgement
>
> Currently the acks (acknowledgement) from the collector are sent back via the
> master(s). In case the master is down, the acks will be lost. It seems that
> the even the multi masters cannot handle this single-point-failure issue.
> A re-design of sending the acks back without getting the master involved will
> be very beneficial. The single-point-failure can be removed to some extent,
> and the efficiency of the acks will also be improved since the master is not
> a bottleneck any more.
