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
Currently: {code} // Master doesn't need data locality ROLES.add(new ProviderRole(HBaseKeys.ROLE_MASTER, KEY_MASTER,PlacementPolicy.NO_DATA_LOCALITY)); {code} But in RoleHistory#findNodeForNewInstance(): {code} if (role.getNoDataLocality()) { return null; } {code} This implies that HBase master instances might be scheduled on one host, obviating the goal for HA. -- This message was sent by Atlassian JIRA (v6.2#6252)
