Description

When i submit this query:
select "time_by_day_alias"."THE_YEAR" as "c0", "git_log_alias"."PROJECT_NAME" as "c1", "git_log_alias"."BRANCH_NAME" as "c2", count(distinct "git_log_alias"."COMMIT_ID") as "m0" from "CODE_VIEW_178E383E_623C_45E3_BA1B_1333DFE2240B" as "git_log_alias" join "TIME_BY_DAY" as "time_by_day_alias" on "git_log_alias"."FORMATED_DATE" = "time_by_day_alias"."THE_DATE" group by "time_by_day_alias"."THE_YEAR", "git_log_alias"."PROJECT_NAME", "git_log_alias"."BRANCH_NAME"

I got following error even though i set kylin.query.scan.threshold=100000000
