Lars Hofhansl commented on HBASE-11195:
---------------------------------------

I'm happy to that (new ticket), just wanted to confirm that I did not miss 
anything. I'll do the fix, and then we'll just release 0.98.12 quickly (right 
[~apurtell] :) )

> Potentially improve block locality during major compaction for old regions

> This might be a specific use case.  But we have some regions which are no 
> longer written to (due to the key).  Those regions have 1 store file and they 
> are very old, they haven't been written to in a while.  We still use these 
> regions to read from so locality would be nice.  
> I propose putting a configuration option: something like
> hbase.hstore.min.locality.to.skip.major.compact [between 0 and 1]
> such that you can decide whether or not to skip major compaction for an old 
> region with a single store file.
> I'll attach a patch, let me know what you guys think.
