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.

Hi Josh
Thanks very much for the reply, I did share the error at the top of the
email
SQL Error [00000]: Error -1 (00000) : Error while executing SQL "ESELECT
PERCENTILE_DISC (0.5) WITHIN GROUP (ORDER BY DECIMALCOLUMN ASC) FROM
TEST.TESTEXCEPTIONS": Remote driver error:
ArrayIndexOutOfBoundsException: (null exception message)
There's a few SQL statements to reliably reproduce the error, I thought
that would be enough but I'm very open to providing any assistance I
can. What further info would be helpful?
Cheers

Simon,
If you have clear bug report, please open up a Jira issue for it. Keep
in mind that as much information as you can provide to indicate the
problem you see, the better. Assume that whoever might read your Jira
issue is coming from zero-context. Right now, you haven't shared any
error, so you're expecting a bit from someone to both help you by first
reproducing the code you've shared, analyze if an error is expected, and
then fix it.
Ideally, you can submit a patch to try to fix the issues you're seeing ;)

If you try the queries marked with BUG below, you get an exception

As far as I can tell I am using the functions correctly.

To reproduce:
Using HBase
HBASE_VERSION=2.0.0
HBASE_MINOR_VERSION=2.0
PHOENIX_VERSION=5.0.0
Connecting using thin client: phoenix-5.0.0-HBase-2.0-thin-client.jar
NOTE: We can't use thick client as I haven't resolved issues connecting
my API which runs inside docker. That's another story.
