> Key: HIVE-20284
> URL: https://issues.apache.org/jira/browse/HIVE-20284
> Project: Hive
> Issue Type: Improvement
> Components: CLI
> Affects Versions: 1.2.1, 2.3.3
> Reporter: Hui Huang
> Assignee: Hui Huang
> Priority: Trivial
> Fix For: 2.3.3, 4.0.0
>
> Attachments: HIVE-20284.1.patch, HIVE-20284.2.patch,
> HIVE-20284.3.patch, HIVE-20284.patch
>
>
> In strict mode and the hive.optimize.constant.propagation is set to true, the
> following sql will failed:
> {code:java}
> hive> desc employee_part;
> OK
> col_name data_type comment
> eid int
> name string
> dept string
> year string
> month string
> # Partition Information
> # col_name data_type comment
> year string
> month string
> Time taken: 0.564 seconds, Fetched: 11 row(s)
> hive> set hive.mapred.mode=strict;
> hive> select * from employee_part where false and concat(year,month)='201807';
> FAILED: SemanticException Queries against partitioned tables without a
> partition filter are disabled for safety reasons. If you know what you are
> doing, please sethive.strict.checks.large.query to false and that
> hive.mapred.mode is not set to 'strict' to proceed. Note that if you may get
> errors or incorrect results if you make a mistake while using some of the
> unsafe features. No partition predicate for Alias "employee_part" Table
> "employee_part"
> {code}
> The above error message is confusing because the expression
> concat(year,month)='201807' is a partition filter。
> The reason is during logic optimization, the ConstantPropagate optimizer is
> running before partitionPruner optimizer, when found a express like 'false
> and concat(year,month)=xxxx', the express is replaced with 'fasle' , and the
> partition filter is dropped. So the PartitionPruner can not get the partition
> filter.
> Users can remove the constant express that always has true/false values to
> work around.
> When views used, if some columns are constant values, users will be
> confusing.
> So we should add some more message in the error msg returned.
