Assignee: (was: Josh Elser)
> Begin replication before WAL is marked as "closed"
> --------------------------------------------------
>
> Key: ACCUMULO-2924
> URL: https://issues.apache.org/jira/browse/ACCUMULO-2924
> Project: Accumulo
> Issue Type: Improvement
> Components: replication
> Reporter: Josh Elser
> Priority: Minor
> Fix For: 1.7.0
>
>
> Presently, we wait for a WAL to be closed before we start replicating the data contained within.
> In an "active" system (one that is continually ingesting a steady stream of data), you don't really notice this lag. In a "fresh" system, there is a noticeable wait before you start to get any replication flowing. This tends to be a pain when you want to verify the correct configuration before walking away for a coffee.
> I don't believe there is anything that would break from removing this check, but it will require a little testing to make sure the edge cases are solid.
