> Add Writable implementations for variable-length integer types.

> Key: HADOOP-850
> URL: http://issues.apache.org/jira/browse/HADOOP-850
> Project: Hadoop
> Issue Type: Improvement
> Components: io
> Affects Versions: 0.10.0

> Priority: Minor
> Fix For: 0.10.0
>
>
> Currently Hadoop supports only three basic integer-like types: ByteWritable,
> IntWritable and LongWritable. They provide a fixed tradeoff between their
> value range and on-disk space consumption. But it is sometimes useful to be
> able to store integer values with broader allowed range, but less space
> consumption when possible.
> This is especially useful when storing very long series of values, combined
> with delta encoding.
> Lucene already implements variable-length encoding for positive int and long.
> I propose to add similar Writable implementations, which use the same
> encoding methods.
