Subject [jira] [Commented] (HDFS-9149) Consider multi datacenter when sortByDistance
Date Sun, 27 Sep 2015 15:09:04 GMT

    [ https://issues.apache.org/jira/browse/HDFS-9149?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14909767#comment-14909767
] 

He Xiaoqiao commented on HDFS-9149:
-----------------------------------

[~He Tianyi] i think it is not necessary to extend {{NetworkTopology}} to satisfy dc aware,
maybe we can improve {{getWeight}} with higher layer in the topology for better locality.

> {{sortByDistance}} doesn't consider multi-datacenter when read data, so there my be reading
data via other datacenter when hadoop deployment with multi-IDC.
