Michael Wall commented on ACCUMULO-4428:
----------------------------------------
When I merged ACCUMULO-4157 up from 1.7 to 1.8, the code for the
GarbageCollectWriteAheadLogs had changed dramatically and could not reproduce
the error in the ticket. So I never implemented the firstSeenDead
Map<HostAndPort,Long> in the 1.8.0 codebase. I did however write a ticket to
look at it more in 1.8, https://issues.apache.org/jira/browse/ACCUMULO-4333.
[~elserj] you ok with me moving this ticket back to 1.8.1 and proceeding with
the rc for 1.8.0?
> 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, 1.8.0
>
>
> 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.
