I think that It's not your mistake. Actually, we should have checked more various cases in
unit tests. 

A local cluster that I mentioned means a single hadoop cluster and a Tajo cluster running
on that cluster. It can be available with a very simple tajo-site.xml as follows. I expect
that you already setup a local cluster.

{code}
<configuration>
  <property>
    <name>tajo.rootdir</name>
    <value>hdfs://localhost:8020/tajo</value>
  </property>

  <property>
    <name>tajo.master.umbilical-rpc.address</name>
    <value>localhost:26001</value>
  </property>

  <property>
    <name>tajo.catalog.client-rpc.address</name>
    <value>localhost:26005</value>
  </property>
</configuration>
{code}

In addition, if you set a launch config in your IDE with two class paths $\{TAJO_HOME}/conf
and $\{HADOOP_HOME}/etc/hadoop, you can directly execute TajoMaster or TajoWorker in your
IDE. It will give more benefits for debugging.

> As we discussed in TAJO-283, column-partitioned store needs hash shuffle phase. The main
objective of this issue is to modify GlobalPlanner to do so.
