Date Wed, 03 Aug 2011 19:50:27 GMT

     [ https://issues.apache.org/jira/browse/HBASE-3857?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

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.
