Chen Liang created HDFS-11998:
---------------------------------
Summary: Enable DFSNetworkTopology as default
Key: HDFS-11998
URL: https://issues.apache.org/jira/browse/HDFS-11998
Project: Hadoop HDFS
Issue Type: Sub-task
Reporter: Chen Liang
Assignee: Chen Liang
HDFS-11530 has made it configurable to use {{DFSNetworkTopology}}, and still
uses {{NetworkTopology}} as default.
Given the stress testing in HDFS-11923 which shows the correctness of
DFSNetworkTopology, and the performance testing in HDFS-11535 which shows how
DFSNetworkTopology can outperform NetworkTopology. I think we are at the point
where I can and should enable DFSNetworkTopology as default.
Any comments/thoughts are more than welcome!
