Encounter cube merge error when deploy kylin on stand alone hbase cluster

suheng.cloud
This post was updated on .
Hi all :

I try to deploy kylin on one node of a stand alone hbase cluster(hdfs://cdh5-mini/) which seperate from main hive cluster(hdfs://cdh5/),
According to the blog "Deploy Apache Kylin with Standalone HBase Cluster" : make sure the configurations of hadoop and hive points to main cluster,
I clone hadoop dir to another path and modify "fs.defaultFS" in core-site.xml to "hdfs://cdh5/" and in head of kylin.sh, I export HADOOP_HOME to this new path.
So all goes well (include cube build/refresh) until I execute cube merge.
The merge error occurs at step "#9 Step Name: Garbage Collection on HDFS".

I couldn’t sovle for a whole day, can you help me to find out if it is configuration error or a bug?
Thanks in advance.

Cluster Versions:
hadoop :cdh5.4.0 (both main and hbase env)
hbase  : hbase-1.2.0-cdh5.7.6
hive: apache-hive-2.1.1

kylin version: 2.0

It seems a bug. Could you open a JIRA for issue?
