--------------------------------------
bq. Happy to work on this and get you a PR – I need to patch the GC anyway and
run it manually to clean up the files. I was thinking of just making the
firstSeenDead map static. I don't see a change like that having any adverse
side effects.
That would be awesome, [~adamjshook]!
> GC does not delete WAL files belonging to dead tservers

> Key: ACCUMULO-4428
> URL: https://issues.apache.org/jira/browse/ACCUMULO-4428
> Project: Accumulo
> Issue Type: Bug
> Affects Versions: 1.7.2
> Reporter: Adam J Shook
> Assignee: Michael Wall
> Priority: Blocker
> Fix For: 1.7.3
>
>
> The GarbageCollectWriteAheadLogs uses a Map<HostAndPort,Long> to track when
> it had first seen a dead tserver, waiting an hour before deleting the files.
> However, a new instance of this class is re-created during each run of the
> SimpleGarbageCollector, causing the state of the dead tservers to be lost.
> All of the WAL files belonging to a dead tserver will never be removed.
