[jira] [Created] (KYLIN-2648) Encounter cube merge error when deploy kylin on stand alone hbase cluster

suheng.cloud created KYLIN-2648:
-----------------------------------

             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". 


The stacktrace  as follows:

Re: [jira] [Created] (KYLIN-2648) Encounter cube merge error when deploy kylin on stand alone hbase cluster

Hi, shaofeng & yang
I try to modiry property "kylin.env.hdfs-working-dir" to full qualified path
" hdfs://cdh5/kylin-83-hadoop",
and found it can't work around.
The error stacktrace is similar as before:
 "Wrong FS:
hdfs://cdh5/kylin-83-hadoop/kylin_metadata/kylin-9e6272e3-d813-481d-82c0-182b85a0ad8f,
expected: hdfs://cdh5-mini"

I checked kylin source, in HDFSPathGarbageCollectionStep.java func doWork:

*dropHdfsPathOnCluster(toDeletePaths, HadoopUtil.getWorkingFileSystem());
            if
(StringUtils.isNotEmpty(context.getConfig().getHBaseClusterFs())) {
                dropHdfsPathOnCluster(toDeletePaths,    
FileSystem.get(HBaseConnection.getCurrentHBaseConfiguration()));
            }*
As long as the property kylin.storage.hbase.cluster-fs(which I set to
hdfs://cdh5-mini) has been set,
Kylin will always try to find and delete the "toDeletePaths" on hbase
cluster,and if we use full qualified path like
"hdfs://cdh5/kylin-83-hadoop",in function dropHdfsPathOnCluster, exception
will be thrown out by the checkpath function since the authority of 
hdfs://cdh5/kylin-83-hadoop/xxx was not equal to the authority of
hdfs://cdh5-mini".So I think it should be a relative path,so kylin check on
both hadoop cluster?

Do we have some other work around way? Or what your standard deploy method
when hbase cluster seperate from main cluster?

I was trying to check if kylin can meet our olap demand,and stuck on this
for a long time, really need your help, thank you!

full log as follows:
