My Hadoop version is 2.6.0-cdh5.4.4 and jdk is 1.8. You can track this
problem at https://issues.apache.org/jira/browse/KYLIN-2654.

Yes, internal comments are good for us to collaborate.

Can you see my comments at https://issues.apache.org/jira/browse/KYLIN-2654.
The website said my comments are internal and only be visible to agents and
collaborators. If you can not, we can communicate by email, I have some
questions want to ask you about this problem. Or we can talk on WeChat if
possible.

I start to suspect this is because Kylin 2.0 is compiled with hadoop 2.7
while Kylin 1.6 is compiled with hadoop 2.6.

Could you confirm your hadoop version and JDK version?

Thanks
Yang
