> I was attempting to prevent blocks from being cached by setting CACHE_BLOCKS 
> => false in the hbase shell when doing a scan but I kept seeing tons of 
> evictions when I ran it. After inspecting "table.rb" I found this line:
> cache = args["CACHE_BLOCKS"] || true
> The problem then is that if CACHE_BLOCKS is false then this expression will 
> always return true. Therefore, it's impossible to turn off block caching.
