Subject [jira] [Created] (KYLIN-1280) Convert Cuboid Data to HFile failed when hbase in different HDFS
Date Mon, 04 Jan 2016 06:21:40 GMT
fengYu created KYLIN-1280:

             Summary: Convert Cuboid Data to HFile failed when hbase in different HDFS
                 Key: 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 : 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.
