-------------------------------
Summary: Unnecessary DNS resolution attempts when NameNodeProxies
Key: HDFS-9364
URL: https://issues.apache.org/jira/browse/HDFS-9364
Project: Hadoop HDFS
Issue Type: Bug
Reporter: Xiao Chen
Assignee: Xiao Chen
When creating NameNodeProxies, we always try to DNS-resolve namenode URIs. This
is unnecessary if the URI is logical, and may be significantly slow if the DNS
is having problems.
