…s variant and log more detailed info for troubleshoot a problem (#59933) Fix query err when calc mv fd by catch it and log more detailed info for troubleshoot a problem 1. originOutputs.size() should equlas targetOutputs.size(), if not would throw exception, this would cause query err, should log err log and not cause query err 2. current log could not find the root cause, so add detail log 3. fix the problem by mapping the slot full path name between scan mv output and mv sql plan output for example as following ```sql CREATE TABLE fact_var ( k INT, v VARIANT ) ENGINE=OLAP DUPLICATE KEY(k) DISTRIBUTED BY HASH(k) BUCKETS 1 PROPERTIES ("replication_num" = "1"); INSERT INTO fact_var VALUES (1, '{"a":1,"b":{"c":10,"d":20}}'), (2, '{"a":2,"b":{"c":30}}'); CREATE MATERIALIZED VIEW mv_var BUILD IMMEDIATE REFRESH COMPLETE ON MANUAL DISTRIBUTED BY RANDOM BUCKETS 2 PROPERTIES ('replication_num' = '1') AS SELECT k, v FROM fact_var; ``` if run query as fllowing, mv_var sacn would return k, v, v['a'] but mv_var def plan sql, would return k, v, the size is different but also can work after the fix ```sql SELECT v['a'] AS c_val FROM mv_var; ``` Related PR: #40106
