I see errors in the log:
java.lang.IllegalArgumentException: No enum constant
org.apache.hadoop.mapreduce
.JobCounter.VCORES_MILLIS_REDUCES
The problem may be my Hadoop version 2.7, according to this JIRA:
https://issues.apache.org/jira/browse/KYLIN-1183.
But: v1.2 and v1.3 run on Hadoop 2.7 without any problem. Maybe you can
check v1.5 to find what was changed. Your suggested Hadoop version is
2.4-2.7. So I work with Hadoop 2.7.

I checked this query in my sandbox with 1.5.0 binary package, it can return
records;
Just check a couple of things:
1. whether the hive table has data;
2. whether the cube has built the date range which covers 2012 to 2013;

Hi,
I installed v1.5 and built the sample cube. All was fine. But when I query
with
select part_dt, sum(price) as total_selled, count(distinct seller_id) as
sellers from kylin_sales group by part_dt order by part_dt
I got No Result / Results (0). Kylin.log shows:
User: ADMIN
Success: true

Project: learn_kylin
Realization Names: [kylin_sales_cube]
Cuboid Ids: [64]
Total scan count: 0
Result row count: 0
Accept Partial: true
Is Partial Result: false
Hit Exception Cache: false
Storage cache used: false
Message: null
I created a cube with my own table and also no results. I installed v1.2
earlier but I deleted all tables (including kylin_metadata) in Hbase. I
think there should be no problem now with version conflict. But I did not
delte Hive table.
What is wrong?
Best regards,
Jie
