Subject [jira] [Created] (HADOOP-10751) HBase Master needs data locality
Date Thu, 26 Jun 2014 02:20:24 GMT
Ted Yu created HADOOP-10751:

             Summary: HBase Master needs data locality
                 Key: HADOOP-10751
                 URL: https://issues.apache.org/jira/browse/HADOOP-10751
             Project: Hadoop Common
          Issue Type: Task
            Reporter: Ted Yu
            Assignee: Ted Yu

    // Master doesn't need data locality
    ROLES.add(new ProviderRole(HBaseKeys.ROLE_MASTER, KEY_MASTER,PlacementPolicy.NO_DATA_LOCALITY));
But in RoleHistory#findNodeForNewInstance():
    if (role.getNoDataLocality()) {
      return null;
This implies that HBase master instances might be scheduled on one host, obviating the goal
for HA.
