this may be caused by Hbase. See the message from Shaofeng:
--------------------------------------------------------------------
v1.5.1 is on the way; it will include a couple of bug fixes; The next
release date hasn't been decided. You will receive the vote email when it
is kick off.

Thanks for the message. You are right, it may be Hbase problem. I have
hbase-0.98.17-hadoop2. It may not be the Hadoop problem because I tested
with Hadoop 2.6 and got the same error:
Java.lang.IllegalArgumentException: No enum constant
org.apache.hadoop.mapreduce
.JobCounter.VCORES_MILLIS_REDUCES
When is the next release? I will wait. Now I work with v1.3. It is fine
with my Hbase and Hadoop.
Best regards,
Jie

Hi Jie,
I compared the hadoop version in 1.5 and 1.3, they are almost the same,
except hbase-hadoop2.version, which is 0.98.8 on v1.3 but 0.98.4 on
v1.5.0). Maybe it has some impactions; if you couldn't wait for next
release, you can clone Kylin's v1.5.0 tag, change the pom.xml, make a new
binary package, and then deploy it in your cluster to see whether it solve
this issue.
Thank you for reporting issue to Kylin!

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.
Best regards,
Jie

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
Duration: 0.172
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

And why cube size is zero, there are data in the hbase table.
