Edward J. Yoon commented on HAMA-900:
-------------------------------------
Cool~
1) % mvn clean install
2) I personally think data locality should have 2nd priority in round-robin.
3) In getClass(String name, Class<? extends U> defaultValue, Class<U>
interface) method, "BestEffortDataLocalTaskAllocator.class" is just a default
value. If you define the "bsp.taskalloc.class" property in hama-site.xml, you
can use it. We may also want to add default configuration to the
hama-default.xml like below:
{code}
<property>
<name>bsp.taskalloc.class</name>
<value>org.apache.hama.bsp.taskallocation.BestEffortDataLocalTaskAllocator</value>
<description>
The task allocator to choose. Default is BestEffortDataLocalTaskAllocator
that
takes in only the data locality as a constraint for allocating tasks.
</description>
</property>
{code}

> To spread tasks widely, I need a FIFO job scheduler that assign tasks one at
> a time in rotation of groom servers (a method of dealing cards).
