Steve Loughran created HADOOP-8630:
--------------------------------------
Summary: rename isSingleSwitch() methods in new topo base class to
isFlatTopology()
Key: HADOOP-8630
URL: https://issues.apache.org/jira/browse/HADOOP-8630
Project: Hadoop Common
Issue Type: Improvement
Components: util
Affects Versions: 2.0.0-alpha, 3.0.0
Reporter: Steve Loughran
Priority: Trivial
The new topology logic that is not yet turned on in HDFS uses the method
{{isSingleSwitch()}} for implementations to declare whether or not they are
single switch.
The use of "switch" is an implementation issue; the big VM-based patch shows
that really it's about "flat" vs "hierarchical", with Hadoop assuming that
subtrees in the hierarchy have better bandwidth (good) but correlated failures
(bad).
Renaming the method now -before it's fixed and used- is time time to do it.
