[jira] Created: (HADOOP-914) Replace use of UTF8 in ObjectWritable
Replace use of UTF8 in ObjectWritable
-------------------------------------
Key: HADOOP-914
URL: https://issues.apache.org/jira/browse/HADOOP-914
Project: Hadoop
Issue Type: Improvement
Reporter: Sami Siren
- Replace use of UTF8 with Text
- Make format a little less verbose, before ObjectWritable containing Text "text" would be stored like:
<UTF8:org.apache.hadoop.io.Text><UTF8:org.apache.hadoop.io.Text><Text:text>
now it is stored as
<Text:org.apache.hadoop.io.Text><Text:text>
-As changes are incompatible they are introduced in a new class 'WrappingWritable', ObjectWritable is deprecated
-Add junit test

Andrzej Bialecki commented on HADOOP-914:
------------------------------------------
The patch looks quite nice, and it would be definitely useful to have this functionality in some situations. However, somehow I don't think we need as many as three similar implementations of this type of containers ... We have ObjectWritable, GenericWritable and WrappingWritable - it's mightily confusing which one should be used in user applications ...
I'm not sure if we shouldn't first try to find a minimum common set of functionality to be implemented in a single base wrapper class, and then extend it for different uses - I think that if we commit this patch there will be a mess ...

-----------------------------------
WrappingWritable deprecates ObjectWritable so I cannot see why it would generate more confusion.
I actually didn't realize there was GenericWritable :). Anyway the motivation for me was nutchs usage of ObjectWritable. But for that case it propably would make more sence to use GenericWritable of better yet write yet one more specialization (into nutch) that can handle it's special case even more effectively than GenericWritable.

Doug Cutting updated HADOOP-914:
--------------------------------
Status: Open (was: Patch Available)
Should I resolve this as "Won't Fix", since you plan to use GenericWritable?
