             Summary: Implement stats annotation rule for the 
                 Key: HIVE-24203
                 URL: https://issues.apache.org/jira/browse/HIVE-24203
             Project: Hive
          Issue Type: Improvement
          Components: Physical Optimizer
    Affects Versions: 2.3.7, 3.1.2, 4.0.0
            Reporter: okumin
            Assignee: okumin

StatsRulesProcFactory doesn't have any rules to handle a JOIN by LATERAL VIEW.

This can cause an underestimation in case that UDTF in LATERAL VIEW generates 
multiple rows.

HIVE-20262 has already added the rule for UDTF.

This issue would add the rule for LateralViewJoinOperator.
