Hyunsik, thanks for your comment.
However, I realized that TaskSchedulerEvent also can be changed according to the task scheduling algorithm, because the required information depends on the algorithms.
So, how about the following configurations?
{code}
<!--- Registered Scheduler Handler -->
<property>
<name>tajo.querymaster.task-scheduler-handler</name>
<value>default</value>
</property>
<!--- Scheduler Configuration -->
<property>
<name>tajo.querymaster.task-scheduler.type</name>
<value>default</value>
</property>
<!--- Scheduler Handler -->
<property>
<name>tajo.querymaster.task-scheduler.default.class</name>
<value>org.apache.tajo.master.DefaultTaskScheduler</value>
</property>
<!-- Scheduler Event handler -->
<property>
<name>tajo.querymaster.task-schedule-event.default.class</name>
<value>org.apache.tajo.master.event.DefaultSchedulerEvent</value>
</property>
{code}
