             Summary: The AggregateRegionObserver class occured error when we compiled the kylin project using hbase-client-1.2.x.jar.ct using hbase-client-1.2.x.jar.
                 Key: KYLIN-2185
                 URL: https://issues.apache.org/jira/browse/KYLIN-2185
             Project: Kylin
          Issue Type: Bug
          Components: Storage - HBase
    Affects Versions: v1.5.4.1, v1.5.2.1, v1.5.3
         Environment: CentOS Linux release 7.2.1511、maven 3.2.5、jdk1.7.0_80

            Reporter: Qiang Zhang
            Assignee: liyang


The return value of the getRegion function in RegionCoprocessorEnvironment interface was different between hbase-client-1.2.x.jar and hbase-client-0.9.8.jar. The getRegion function was called and the return value didn't appropriately converted in the AggregateRegionObserver class. So the AggregateRegionObserver class occured error when we compiled the kylin project using hbase-client-1.2.x.jar.
The reappear steps is as following:
1. Get source code using git from git://git.apache.org/kylin.git;
2. Run the mvn command to compile the kylin project;
3. Compile successfully;
4. Modify the value of the <hbase-hadoop2.version> to 1.2.0 in the pom.xml of the kylin project;
5. Run the mvn command to compile the kylin project;
3. Compile fail;
