I've run into this issue when attempting to use Phoenix with both R Studio (with RJDBC), as well as ElasticSearch
Lots of libraries attempt a setFetchSize() on a JDBC result set, but very few of them have error handling code, unfortunately. Rather than attempting to patch each library, it would be nice if Phoenix could handle this call.
Is it as simple as invoking "statement.setFetchSize()" in this method?
I suspect not, but if someone can take a quick look I can make the necessary code change and submit a patch.
