Summary: Encounter cube merge error when deploy kylin on stand
alone hbase cluster
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: Dong Li
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".
