Mikhail Bautin updated HBASE-3857:
----------------------------------
Attachment: 0001-review_hfile-v2-r1153300-git-1152532-2011_08_03_12_4.patch
Addressing the issue with TestHFileBlock reported by Ted. It turns out there is
an "OS" field inside the gzip header which might take different values
depending on the OS and configuration. I have changed the unit test to always
set that field to the same value before comparing.
