Subject is it possible to view the number of hfiles a GET touches in hbase?
Date Fri, 10 Aug 2012 11:17:09 GMT
Hi,
Given a GET() operation, I want to monitor the number of on-disk hfiles it
touches? GET() may need to
check every in-memory hfiles (block index),  but don't need to touch every
on-disk parts of hfiles. I want to know
how many disk hfile a GET() accesses, that is, how many disk IO a GET() end
up with...

is it possible to obtain this information without hack into hbase source
code?
Richard
