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).

>             Project: Apache Drill
>          Issue Type: Bug
>          Components: Storage - HBase

>            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).
