(from hdfs-2246 release notes). It is red herring though because when you set hbase.regionserver.checksum.verify, in hbase, we set the above config. to true. See HFileSystem. It is news to me we read the .meta file even though we ask for no checksumming. Its a bug I'd say. Do you have the fb commit that skips this seek? No worries if you do not. I can find it myself.
