---------------------------------

             Summary: query failed because scan threshold
                 Key: KYLIN-2488
                 URL: https://issues.apache.org/jira/browse/KYLIN-2488
             Project: Kylin
          Issue Type: Bug
          Components: Query Engine
    Affects Versions: v1.6.0
            Reporter: zhou degao
            Assignee: liyang
         Attachments: cube.PNG

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
