> The test came in recently as part of HBASE-17712 "Remove/Simplify the logic of RegionScannerImpl.handleFileNotFound"
> [~Apache9] when you have a chance, help me out. I was going to just remove the test since
it made no sense to me but then I saw you wrote it  (smile).
> When the region.compact(true); is called on the end, what is supposed to be going on?
> When I trace, the compact is not done because the Region is not writeEnabled (we check
if Region is writeEnabled down in Store before we go ahead and compact). So, I thought the
problem was that the region reference was stale because it came from the rsToSuspend which
had just been killed.
> After a while, I figured that you intend the region reference to be stale so you can
try an append AFTER the WAL has been taken over by WAL splitter.
> But the writeEnabled flag is set so compactions don't run. I tried unsetting this flag
and closed flags and but compaction won't run.
> Was this your intent sir? If so, I'll work w/ it np. Just looking for clarity. Thanks.
