Doğacan Güney commented on NUTCH-527:
-------------------------------------
What was the error you were having? MapWritable supports reading and writing
*all* writables. The ones defined at the top of the file are an optimization
and shouldn't affect correctness (basically mapwritable first writes a byte and
the associated classname, then writes that byte to indicate classname
everywhere else. For commonly used types we statically define the association
so that "first write the byte then the classname" phase is not necessary).
> MapWritable doesn't support all hadoops writable types

> Key: NUTCH-527
> URL: https://issues.apache.org/jira/browse/NUTCH-527
> Project: Nutch
> Issue Type: Bug
> Affects Versions: 0.9.0
> Environment: Tested on Solaris and Windows with Java 1.5
> Reporter: Rob Young
> Attachments: mapwritable.patch

>
> The map of classes which implement org.apache.hadoop.io.Writable is not
> complete. It does not, for example, include
> org.apache.hadoop.io.BooleanWritable. I would happily provide a patch if
> someone would explain what the Byte parameter is.
