I ran:
Query: create table last_loop_pq stored as parquet as select key1,key2,prev1,prev2 from integrationtestbiglinkedlist where client between 'Job: job_1439762566588_0117' and 'Job: job_1439762566588_0118'
and the plan in Impala is showing:
00:SCAN KUDU [default.integrationtestbiglinkedlist] kudu predicates: client >= 'Job: job_1439762566588_0117', client <= 'Job: job_1439762566588_0118' hosts=71 per-host-mem=0B
but the /scanz page on a Kudu TS isn't showing any pushed predicates.
