Some folks I'm working with have been wanting this to make replication more predictive. Definitely a nice bonus which gets around a quick of the replication impl. bq.

I'd like to better understand why we need to change our code. > open WALs prevent DN decommissioning > ------------------------------------ > > Key: ACCUMULO-4004 > URL: https://issues.apache.org/jira/browse/ACCUMULO-4004 > Project: Accumulo > Issue Type: Improvement > Components: tserver > Reporter: Eric Newton > Assignee: Eric Newton > Fix For: 1.6.6, 1.7.2, 1.8.0 > > Attachments: ACCUMULO-4004-1.patch > > Time Spent: 10m > Remaining Estimate: 0h > > It should be possible to manually roll WALs so that files on decommissioning datanodes are closed and the decommissioning process can complete.
