>         Attachments: variable-ints.patch
> 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
> Lucene already implements variable-length encoding for positive int and long. I propose
to add similar Writable implementations, which use the same encoding methods.
