Subject [jira] [Updated] (HDFS-2048) 1073: Improve upgrade tests from 0.22
Date Wed, 08 Jun 2011 00:05:59 GMT

     [ https://issues.apache.org/jira/browse/HDFS-2048?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Todd Lipcon updated HDFS-2048:
------------------------------

    Attachment: hdfs-2048.txt

Patch includes a new test case which tests upgrade from the 0.22 image, but before doing so,
corrupts the md5 sum stored in the version file. This also fixes a bug in the upgrade path
so that this test case passes.

> TestDFSUpgradeFromImage currently tests an upgrade from 0.22, but doesn't test that the
image checksum field is properly respected during the upgrade.
> This JIRA is to improve those tests by also testing the case where the image has been
corrupted.
