[jira] [Updated] (HDFS-12990) Change default NameNode RPC port back to 8020
[ https://issues.apache.org/jira/browse/HDFS-12990?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ] Anu Engineer updated HDFS-12990: Resolution: Fixed Hadoop Flags: Incompatible change,Reviewed (was: Incompatible change) Fix Version/s: 3.0.1 Status: Resolved (was: Patch Available) [~xiaochen] Thanks for the contribution, I have committed this to trunk and 3.0.1. To all others who commented, Thank your comments. I will mail the lists about this change so that people are mindful if they deploy 3.0.0 or they wait for 3.0.1. [~eddyxu] When you send out the voting thread for 3.0.1, you might want to call this JIRA out and deprecate 3.0.0. > Change default NameNode RPC port back to 8020 > - > > Key: HDFS-12990 > URL: https://issues.apache.org/jira/browse/HDFS-12990 > Project: Hadoop HDFS > Issue Type: Task > Components: namenode >Affects Versions: 3.0.0 >Reporter: Xiao Chen >Assignee: Xiao Chen >Priority: Critical > Fix For: 3.0.1 > > Attachments: HDFS-12990.01.patch > > > In HDFS-9427 (HDFS should not default to ephemeral ports), we changed all > default ports to ephemeral ports, which is very appreciated by admin.
