How to use NiFi to query Kudu backed Impala tables

I'm running some PoC in a 3 nodes CDH cluster and trying to use NiFi to query some Kudu backed Impala tables.

As Impala supports the JDBC connection, you can easily set up a NiFi DBCP connection pool, then use the ExecuteSQL processor to get data out of Impala tables backed by Kudu. Hope that helps.

Thanks @dsun I'll test it out and accept the answer if it works.
