Jean-Daniel Cryans commented on HBASE-2752:
-------------------------------------------
This is something that Dave Latham was hitting when trying out 0.20.5 RC3. One
of his region server was compacting non-stop and a region could be blocked for
minutes.
> Don't retry forever when waiting on too many store files

> HBASE-2087 introduced a way to not block all flushes when on region has too
> many store files. Unfortunately, that undid the behavior that if we waited
> for longer than 90 secs then that we would still flush the region... which
> means that when a region blocks inserts because its memstore is too big it's
> actually holding off writes for a very long time, occupying handlers, etc.
> We need to add more smarts in MemStoreFlusher so that we detect when a region
> was held up for too long.
