this issue.
> MapWritable.equals() doesn't work properly
> ------------------------------------------
>
> Key: NUTCH-263
> URL: http://issues.apache.org/jira/browse/NUTCH-263
> Project: Nutch
> Type: Bug
> Versions: 0.8-dev
> Reporter: Andrzej Bialecki
> Attachments: patch1.txt
>
> MapWritable.equals() is sensitive to the order in which map entries have been
> created. E.g. this fails but it should succeed:
> MapWritable map1 = new MapWritable();
> MapWritable map2 = new MapWritable();
> map1.put(new UTF8("key1"), new UTF8("val1"));
> map1.put(new UTF8("key2"), new UTF8("val2"));
> map2.put(new UTF8("key2"), new UTF8("val2"));
> map2.put(new UTF8("key1"), new UTF8("val1"));
> assertTrue(map1.equals(map2));
> Users expect that this should not be the case, i.e. this class should follow
> the same rules as Map.equals() ("Returns true if the given object is also a
> map and the two Maps represent the same mappings").
