Impala JDBC Driver - AutoCommit and TPC-C

[#1]

Hello.

I am trying to run a TPC-C benchmark on Impala with Kudu and therefore completed the necessary system installation and JDBC driver download. However, the driver documentation states that the AutoCommit feature is always set to true, which means explicit commits and rollbacks are not possible. 

I am therefore wondering, if the TPC-C benchmark can be valid when using the Impala JDBC driver, as the TPC-C specification states that rollbacks must happen at a fixed rate? Is there a workaround that can be used instead?

Thanks for your time.

Impala is not designed for traditional OLTP and doesn't have transaction support that would line up with what TPC-C expects.
