Jean-Marc Spaggiari commented on HBASE-9648:
--------------------------------------------
Is the region really empty? From the logs provided by the user we can see this:
{code}
size=491.0; total size for store is 5.7m
{code}
491 bytes is very small, I agree, but might not be totally empty.
> collection one expired storefile causes it to be replaced by another expired
> storefile

> Project: HBase
> Issue Type: Bug
> Components: Compaction
> Reporter: Sergey Shelukhin
>
> There's a shortcut in compaction selection that causes the selection of
> expired store files to quickly delete.
> However, there's also the code that ensures we write at least one file to
> preserve seqnum. This new empty file is "expired", because it has no data,
> presumably.
> So it's collected again, etc.
> This affects 94, probably also 96.
