Summary: Optimize 'setTableStats' for the Iceberg tables without
stats in HMS
Key: IMPALA-11681
URL: https://issues.apache.org/jira/browse/IMPALA-11681
Project: IMPALA
Issue Type: Improvement
Reporter: LiPenglin
For the Iceberg tables, when we cannot get the table Parameters
StatsSetupConst.ROW_COUNT and StatsSetupConst.TOTAL_SIZE from HMS, It can be
retrieved from Iceberg's meta. This is the appropriate ordering for the join of
the Iceberg tables without stats.
