Hello,

How can I see in Impala that partition pruning happening with Kudu tables?

When I do an EXPLAIN plan on my query or see profile, I do not see anything
that would indicate that Impala filtered partitions.

With Impala on HDFS, I can clearly see if only a few partitions were used.
For example

| 00:SCAN HDFS [stg.events]                    |
|    partitions=2/30 files=2 size=14B


With Kudu, I am getting something like this (table is hash partitioned by
source_system_id)


00:SCAN KUDU [cerner.test2]   kudu predicates: source_system_id = 333
   mem-estimate=0B mem-reservation=0B
   tuple-ids=0 row-size=31B cardinality=unavailable


Thanks,
Boris
