See bottom for the only stacktrace I can get at, once I hit
org.apache.calcite.avatica.AvaticaSqlException I can no longer step down the
backtrace as it's just a loop.
To do a Unit test I would presumably have to be able to compile hbase, that's
a fairly protracted process and then a fix would have to ripple up all the way
to AWS EMR version, which I'm guessing would be months away.
I'm not ducking the work, I would be interested in doing whatever I can to help
the fix process. I'm just reading through the build instructions and panicking
slightly. This would be my first open source contribution so I'm sure there
will be bumps in the road.
Cheers

Subject: Re: Unable to use some functions on DECIMAL columns
Any stacktrace? An error message on its own isn't too helpful (as it
could come from any number of places).
We have lots of unit tests in the project. Ideally, a unit test which
illustrates the error is the best way for someone to start poking at the
problem. Figuring out if it's a problem unique to the thin-client or if
it affects both the thin-client and thick-client is important.
