Subject [jira] [Commented] (HAMA-900) Rotation task scheduler
Date Fri, 15 Jan 2016 01:17:39 GMT

    [ https://issues.apache.org/jira/browse/HAMA-900?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15099245#comment-15099245

Edward J. Yoon commented on HAMA-900:


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:

      The task allocator to choose. Default is BestEffortDataLocalTaskAllocator that
      takes in only the data locality as a constraint for allocating tasks.

> 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).
