Subject [jira] Resolved: (HADOOP-6827) Extend the API of NetworkTopology
Date Wed, 01 Sep 2010 02:32:54 GMT

Rodrigo Schmidt resolved HADOOP-6827.

    Resolution: Won't Fix

In HDFS-1094, we decided to use the includes file instead of the network topology to define
the groups of nodes in which blocks can be replicated.

>          Issue Type: New Feature

>            Assignee: Rodrigo Schmidt
> The current API for NetworkTopology is too restricted (and somehow biased towards the
default block placement algorithm). 
> For instance, it lacks methods to list racks or limit machines within a rack which are
fundamental for HDFS-1094.
