>
> Key: KYLIN-2648
> URL: https://issues.apache.org/jira/browse/KYLIN-2648
> Project: Kylin
> Issue Type: Bug
> Components: Job Engine
> Affects Versions: v2.0.0
> Environment: 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
> Reporter: suheng.cloud
> Assignee: liyang
> Fix For: v2.1.0
>
>
> 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".
