> Comparison of timestamp fails if only date part is provided.

> Key: HIVE-15291
> URL: https://issues.apache.org/jira/browse/HIVE-15291
> Project: Hive
> Issue Type: Bug
> Components: Hive, UDF
> Affects Versions: 2.1.0
> Reporter: Dhiraj Kumar
> Assignee: Dhiraj Kumar

>
> Summary : If a query needs to compare two timestamp with one timestamp
> provided in "YYYY-MM-DD" format, skipping the time part, it returns incorrect
> result.
> Steps to reproduce :
> 1. Start a hive-cli.
> 2. Fire up the query -> select cast("2016-12-31 12:00:00" as timestamp) >
> "2016-12-30";
> 3. Expected result : true
> 4. Actual result : NULL
> Detailed description :
> If two primitives of different type needs to compared, a common comparator
> type is chosen. Prior to 2.1, Common type Text was chosen to compare
> Timestamp type and Text type.
> In version 2.1, Common type Timestamp is chosen to compare Timestamp type and
> Text type. This leads to converting Text type (YYYY-MM-DD) into
> java.sql.Timestamp which throws exception saying the input is not in proper
> format. The exception is suppressed and a null is returned.
> Code below from org.apache.hadoop.hive.ql.exec.FunctionRegistry
> {code:java}
> if (pgA == PrimitiveGrouping.STRING_GROUP && pgB ==
> PrimitiveGrouping.DATE_GROUP) {
> return b;
> }
> // date/timestamp is higher precedence than String_GROUP
> if (pgB == PrimitiveGrouping.STRING_GROUP && pgA ==
> PrimitiveGrouping.DATE_GROUP) {
> return a;
> }
> {code}
> The bug was introduced in
