             Summary: Convert Cuboid Data to HFile failed when hbase in different HDFS
                 Key: KYLIN-1280
                 URL: https://issues.apache.org/jira/browse/KYLIN-1280
             Project: Kylin
          Issue Type: Bug
    Affects Versions: 2.0
            Reporter: fengYu


I deploy kylin-2.0 with hbase which rely on a different HDFS with hadoop cluster, so I config this property 'kylin.hbase.cluster.fs' = hdfs://A, the name service is different with 'fs.defaultFS' in hadoop cluster which is hdfs://B.

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. Local configuration does not have a failover proxy provide
r configured.

I think it is because node manager in hadoop cluster can not recognition hdfs://A in they config. 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.  
Here is my patch.
