The Apache Impala (incubating) 2.8.0 sources do carry the default flush mode of Kudu client sessions as AUTO_FLUSH_BACKGROUND: https://github.com/apache/incubator-impala/blob/2.8.0/be/src/exec/kudu-table-sink.cc#L161-L162 (in 2.7.0 this was MANUAL)
The CDH 5.10.0 included Apache Impala (incubating) release too has the default flush mode set to AUTO_FLUSH_BACKGROUND as evidenced at https://github.com/cloudera/Impala/blob/cdh5.10.0-release/be/src/exec/kudu-table-sink.cc#L161-L162 .
