In the step 'Convert Cuboid Data to HFile' execute failed, error log is :
java.io.IOException: Failed to run job : Unable to map logical nameservice URI 'hdfs://A' to a NameNode.

So, I have to tranform the path hdfs://A/path/to/hfile to hdfs://namenode_ip:port/path/to/hfile before execute this step. and it works for me. I have create a jira here : https://issues.apache.org/jira/browse/KYLIN-1280 If you have a better solution, reply me please.
