Placeholder error with clickhouse-jdbc and pxf

[dlkrt]

Использую драйвер 0.6.3 clickhouse-jdbc в pxf greenplum com.clickhouse.jdbc.ClickHouseDriver. Сразу скажу, все указанное далее не воспроизводится при прямом подключении к клику, только с bulk. Две проблемы:

Авторизация при указании кредов в jdbc.user jdbc.password не работает. Пытается автоизоваться с default юзером. Фикс - указать креды в query_params или Autorization: basic header.

Если обходим, выполняются несколько select запросов

Затем драйвер пишет ошибку
PXF server error : Can't set parameter at index 1 due to no JDBC style '?' placeholder found in the query
И новых запросов нет. Как-то можно починить?
