Extend the API of NetworkTopology
---------------------------------
Key: HADOOP-6827
URL: https://issues.apache.org/jira/browse/HADOOP-6827
Project: Hadoop Common
Issue Type: New Feature
Reporter: Rodrigo Schmidt
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.
