Subject [jira] Commented: (MAPREDUCE-808) Buffer objects incorrectly serialized to typed bytes
Date Mon, 03 Aug 2009 13:53:15 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-808?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12738344#action_12738344

Klaas Bosteels commented on MAPREDUCE-808:
------------------------------------------

The failed tests seem to be ones that have been failing on Hudson for quite a while now (and
thus are not related to the patch).

> {{TypedBytesOutput.write()}} should do something like
> {code}
> Buffer buf = (Buffer) obj;
> writeBytes(buf.get(), 0, bug.getCount());
> {code}
> instead of
> {code}
> writeBytes(((Buffer) obj).get());
> {code}
> since the bytes returned by {{Buffer.get()}} are "only valid between 0 and getCount()
- 1".
