Hi everyone, I'm wondering if it's possible to lazily deserialize a Writable. That is, when my custom Writable is handed a DataInput from readFields, can I simply hang on to the reference and read from it later? This would be useful if the Writable is a complex data structure that may be expensive to deserialize, so I'd only want to do it on-demand. Or does the runtime mutate the underlying stream, leaving the Writable with a reference to something completely different later?
I'm wondering about both present behavior, and the implicit contract provided by the Hadoop API. Thanks! -Jimmy
