Subject [jira] [Commented] (HBASE-9297) Fix HFileV1Detector tool post HBASE-9126
Date Thu, 22 Aug 2013 17:31:52 GMT

    [ https://issues.apache.org/jira/browse/HBASE-9297?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13747689#comment-13747689

Himanshu Vashishtha commented on HBASE-9297:
--------------------------------------------

So, the major version of any hfile is in the last int value of the file. I don't need to read
the entire FixedFileTrailer. Tested it with both HFileV1 and HFileV2 and it looks good.

> We need to detect any HFileV1 before upgrading to 0.96. The code to read HFileV1 version
is removed in HBASE-9126. It breaks HFileV1Detector tool.
