Can you sure that the local Hadoop cluster can use the hdfs://kylin to 
read/write the hdfs of hbase cluster?

Which step you get this exception? Can you get more details information?
And, I recommend use Ambari HDP to deploy your environment.

You can check your jackson version. I think that if your jackson version not

I think your kylin server not share one metadata. Maybe you kylin configuration

fact table has one lookup table;  

5 dimensions , in which 4 dimensions' encoding are fixed length,  separately 
the length are 9, 8, 8, 33 ;

RE: Can't build and refresh job

[Yapu Jia]

I had checked it in the job list. It not have any running or error job for the 
cube.
If there have any running or error job about this cube. I think I can't use 
others Kylin server to build and refresh it.
In this case, it may be a Kylin bug.

problem about build development env

[Yapu Jia (Person Consulting)]

Hi,
I use the Hortonworks Sandbox 2.2.4 to bulid my development env.

mvn test -Dtest=org.apache.kylin.job.BuildIIWithEngineTest

The failure info is

Therefore, I don't kown how fix it. I skip the step (Run unit trests) and go to 
next step (lunch Kylin Web Server).
There have a problem is that I can't lunch org.apache.kylin.rest.DebugTomcat . 
The error is "Selection does not contain a main type".

So, how to fix these problem and build development env about Kylin.

Thanks,
Yapu
