Because a few real changes were made to this class (it isn't just copying
the source to avoid including the jar that contains it) it would be good to
have an explicit pointer to the version of this class that this was based on.
Is this pulled out of the Hadoop source at the commit tagged for the 2.7.1
release?
It might have been cleaner to do this in two commits, one just checking in
the class exactly as it appears in Hadoop, with just the packaged changed and a
follow up commit the with refactoring to remove the dependencies imported in
the hadoop version of the class. At least a mention of a commit ID this was
pulled out of would give a pointer to the exact version this was based on if we
ever had to apply a patch from Hadoop mainline that didn't merge cleanly.

> Hi,
> We are using the 1.5-SNAPSHOT version of the JDBC drilver (all) and we seem
> to be getting this old thing:
> https://issues.apache.org/jira/browse/DRILL-2482
> We are either doing something wrong or this or this is a regression. Has
> anyone else experienced not being able to get nested structures via the
> latest JDBC driver?
> (I'm going to pull the lastest from master to be sure this has not been
> solved)
> The error we get when accessing a field containing a sub-structure is :
> java.lang.NoClassDefFoundError: org/apache/hadoop/io/Text
