I took this from the source jar of the Hadoop 2.7.1 release, not a
particular commit. That is why I noted that origin in the comment at the top of
the file. Looking at how Hadoop tags, that looks it is the same as
ac0538aac347bfd97cc0dee1db49db503c15f1d9 but I think the version number should
suffice. Good idea on the two commits. I'll do that in the future if I need to
do this kind of thing again.

> Project: Apache Drill
> Issue Type: Bug
> Components: Client - JDBC
> Affects Versions: 0.5.0
> Environment: Linux / 1.5-SNAPSHOT
> Reporter: Stefán Baxter
> Assignee: Jason Altekruse
>
> 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
