Description
When rewriting MV insert overwrite plan to incremental rebuild plan a Sum0 aggregate function is used when aggregating count function subresults coming from the existing MV data and the aggregated newly inserted/deleted records since the last rebuild
create materialized view mat1 stored as orc TBLPROPERTIES ('transactional'='true') as select t1.a, count(*) from t1
Insert overwrite plan:
HiveAggregate(group=[{0}], agg#0=[$SUM0($1)])
HiveUnion(all=[true])
HiveAggregate(group=[{0}], agg#0=[count()])
HiveProject($f0=[$0])
HiveFilter(condition=[<(2, $5.writeid)])
HiveTableScan(table=[[default, t1]], table:alias=[t1])
HiveTableScan(table=[[default, mat1]], table:alias=[default.mat1])
AssertionError when rewriting the plan to incremental rebuild
