Still a problem in Drill 1.12.
Looking at log/sqlline.log, I can see the following error:

So it seems that the patching is failing, which I assume is because the
Stopwatch class has already been loaded prior to the patching, which causes the
duplicate class definition error
([https://stackoverflow.com/questions/40105981/changing-a-class-with-javassist-java-reflexion]).
-Moving forward, I think to fix this issue, we should update the HBase client
version (currently at 1.1.3), since HBase client no longer uses Stopwatch
(https://issues.apache.org/jira/browse/HBASE-14963). Is there any reason why
we're still using 1.1.3?-
Since the latest stable version of HBase (1.2.6) still uses Guava 12.0.1, I
think we should shade hbase-client to use the older Guava version, instead of
patching it. I'll give it a try, and if it works, I'll submit a patch soon.

> Key: DRILL-4931
> URL: https://issues.apache.org/jira/browse/DRILL-4931
> Project: Apache Drill
> Issue Type: Bug
> Components: Storage - HBase
> Affects Versions: 1.8.0
> Reporter: T.C. Hydock
> Priority: Major
>
> I was attempting to follow the "Querying HBase Data" tutorial
> (https://drill.apache.org/docs/querying-hbase/) against one of our HBase
> instances and ran into the following error when trying to issue the "SELECT *
> FROM students;" statement cited in Step #2 of the "Query HBase Tables"
> section:
> {noformat}
> Error: SYSTEM ERROR: IllegalAccessError: tried to access method
> com.google.common.base.Stopwatch.<init>()V from class
> org.apache.hadoop.hbase.zookeeper.MetaTableLocator
> {noformat}
> After doing some research it appears to be a conflict with instantiating the
> Stopwatch class from the Guava JAR. I was able to resolve this by swapping
> out the packaged version of Guava (v18) with an older version (v16).
