Subject [jira] [Updated] (HDFS-4705) TestAllowFormat fails on Windows because of invalid dfs.namenode.name.dir
Date Sat, 20 Apr 2013 23:03:15 GMT

Ivan Mitic updated HDFS-4705:

    Attachment: HDFS-4705.2.patch

Hi Chris,

I spent some time thinking here, and wasn’t able to come up with anything better than what
you suggested. Basically, the value for {{dfs.namenode.name.dir}} ends up being an invalid
URI on Windows because of how its value is expanded. In production, passing a valid URI will
work, so we don’t have any problems. In test, reasonable approach is to be explicit and
set {{dfs.namenode.name.dir}} to a value that is a valid URI on both Unix and Windows platforms.

I went ahead and fixed all above tests with the similar approach. This will get all of them
to pass, with the exception of TestCheckpoint, which will continue to fail on Windows for
a different reason.

Let me know if you have any feedback on the patch. And big thanks for your proactive help!
