Matteo Bertozzi commented on HBASE-11011:
-----------------------------------------
{quote}The fact that a file is missing seems pretty bad, yet it's at
DEBUG.{quote}
In this case is not bad, is an "expected" situation, where the RS died before
moving the compacted file.
Anyway, I think that all the "for(compactionOutputs)" loop can be removed,
since is trying to lookup files in /table/region/family/ and if they are there
are already loaded for sure.
> Avoid extra getFileStatus() calls on Region startup

> On load we already have a StoreFileInfo and we create it from the path,
> this will result in an extra fs.getFileStatus() call.
> In completeCompactionMarker() we do a fs.exists() and later a
> fs.getFileStatus()
> to create the StoreFileInfo, we can avoid the exists.
