Specifying multiple hosts when connecting to Impala over JDBC

Hi,

Is it possible to specify multiple hosts when connecting to Impala over
JDBC, for fail-over purposes?

Regards,

Hello,

Failover would have to be handled by the JDBC client so it's outside
of Impala's scope. Using HAProxy to route connections is fairly
common.
