Summary: Add predicates line in plan output for partition key
predicates
Key: IMPALA-7919
URL: https://issues.apache.org/jira/browse/IMPALA-7919
Project: IMPALA
Issue Type: Improvement
Components: Frontend
Reporter: Greg Rahn
When there is a predicate on a partitioned table's partition key column the
SCAN node does not print the "predicates" line as it would if the table was not
partitioned. IMO predicates should always be included in the nodes where they
are applied irregardless of partitioning or not to make it clear.
Query:
{noformat}
select * from t1 where part_key=42;
{noformat}
>From a non-partitioned table:
{noformat}
00:SCAN HDFS [default.t1]
partitions=1/1 files=2 size=10B
predicates: default.t1.part_key = 42
{noformat}
>From a non-partitioned table:
{noformat}
00:SCAN HDFS [default.t1]
partitions=1/2 files=1 size=2B
{noformat}
