Hi, is it possible to reverse the sort-order? I mean, it seems the reducers are getting the output in descending order. As I want to sort wikipedia revisions of articles it would be great in ascending order. Now the output on a simple little test file is (sorted/grouped automatically by Map/Reduce):
<page><id>774932</id><title>foo</title><revision><id>89865</id><timestamp>2003-11-21T02:12:21Z</timestamp><text>dshajkl</text></revision></page> <page><id>774932</id><title>foo</title><revision><id>233192</id><timestamp>2002-12-20T02:12:21Z</timestamp><text>blaaaaa</text></revision></page> <page><id>732819</id><title>blubb</title><revision><id>233192</id><timestamp>2001-02-21T02:12:21Z</timestamp><text>tztztz</text></revision></page> <page><id>372819</id><title>bla</title><revision><id>233192</id><timestamp>2001-01-21T02:12:21Z</timestamp><text>blaaaaa</text></revision><revision><id>e7777</id><timestamp>2001-01-21T02:12:21Z</timestamp><text>blubb</text></revision></page> <page><id>732819</id><title>blubb</title><revision><id>233192</id><timestamp>2000-01-20T02:12:21Z</timestamp><text>blaaaaa</text></revision></page> The reverse order would be great. BTW: I would like to add a root-Element, since XML requires a root node. I assume it's not possible to determine if the first and last reduce-Job is running!? regards, Johannes
