Subject [jira] [Commented] (HBASE-18889) Different namenodes url but the same location in are treated differently
Date Fri, 29 Sep 2017 21:27:00 GMT

    [ https://issues.apache.org/jira/browse/HBASE-18889?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16186447#comment-16186447
] 

Biju Nair commented on HBASE-18889:
-----------------------------------

In a multi namenode scenario (which will be HDFS HA), it would be better use the HDFS service
name instead of the individual NN hostnames since any one can be an active NN.  By using the
HDFS service name, is this still an issue?
