Subject Re: Array data types

Hi Mike,

Yes, this is a known missing feature in Apache Avatica, the tech behind the
thin client/query server. I've recently committed the implementation in
Avatica, we just need to cut a new release upstream and also here in

The workaround is to use the thick client or avoid the use of arrays with
the thin client at present.

We are getting a “Remote driver error: UnsupportedOperationException:
Currently not supported” error when querying an hbase table in an EMR 5.4
cluster using the phoenix-4.9.0-HBase-1.2-thin-client.jar.

The error occurs when doing a select on a table that has one or more
columns with Array data type.  When I remove the Array columns from the
select clause, the query runs without error.  I did some research on this
problem and it seems to be a bug documented in We would like to know if this
behavior was reported to you before, and if so, what is your recommended
workaround or solution.  Thanks for looking at this
