Zhe Zhang commented on HDFS-9364: --------------------------------- Thanks Xiao for updating the patch and verifying Jenkins results. Agreed that {{testHedgingWhenOneFails}} is the only seemingly related failure. I verified that the test doesn't trigger the changed code. +1, I will commit the patch shortly. > Unnecessary DNS resolution attempts when creating NameNodeProxies > ----------------------------------------------------------------- > > Key: HDFS-9364 > URL: https://issues.apache.org/jira/browse/HDFS-9364 > Project: Hadoop HDFS > Issue Type: Bug > Components: ha, performance > Reporter: Xiao Chen > Assignee: Xiao Chen > Attachments: HDFS-9364.001.patch, HDFS-9364.002.patch, > HDFS-9364.003.patch, HDFS-9364.004.patch > > > 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. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
