Hello Impala Public Jenkins, Alex Behm,
I'd like you to reexamine a change. Please visit
http://gerrit.cloudera.org:8080/6389
to look at the new patch set (#23).
Change subject: IMPALA-5003: Constant propagation in scan conjuncts
......................................................................
IMPALA-5003: Constant propagation in scan conjuncts
Implements constant proopagation within conjuncts and applies the
optimization to scan conjuncts and collection conjuncts within Hdfs
scan nodes. The optimization is applied during planning. At scan
nodes in particular, we want to optimize to enable partition pruning.
In certain cases, we might end up with a FALSE conditional, which
now will convert to an EmptySet node.
Testing: Expanded the test cases for the planner to achieve constant
propagation. Added Kudu, datasource, Hdfs and HBase tests to validate
we can create EmptySetNodes.
