b746978c71ce4a95b69d49c43d0ac852909a8b4e KUDU-2671: Follow up pruning patch.
This patch flattens the result set of the pruner into a one
dimensional container. The new container only contains the
partition key ranges and no longer stores the range bounds.
Currently, full scans using KuduScanner with no predicates are
functional. Scans with range predicates are also functional on
tables with covering ranges as well as on tables with non
covering ranges.
There are a few commented out test cases within
flex_partitioning_client-test. These test cases involve a scan
with range predicates that are both out of bounds. They fail
because the non covering range case is triggered in
scanner_internal and we return early from this function before
the proxy_ is set. Check(proxy_) is where the tests fails in
KuduScanner::NextBatch within client.cc.
Using KuduScanTokens to scan tables with range specific hash schemas
is not yet compatible. A follow up patch should address this deficiency.
The scan token tests with custom hash schemas are failing when
verifying the tablet info. It seems that the data_ field of the
KuduTablets isn't set.
