-----------------------------
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.
