Mike Percy commented on KUDU-2563:
----------------------------------
It appears that we'll have to expose scanner keepalive to the Java API before
implementing Spark support, because the only place I see the keepalive API
defined is in the C++ client KuduScanner class @
http://kudu.apache.org/releases/1.7.1/cpp-client-api/classkudu_1_1client_1_1KuduScanner.html#aa4a0caf7142880255d7aac1d75f33d21
> Spark integration should implement scanner keep-alive API
