Subject [jira] [Commented] (ACCUMULO-4428) GC does not delete WAL files belonging to dead tservers

Josh Elser commented on ACCUMULO-4428:
--------------------------------------

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]!

> 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.
