Subject [jira] [Commented] (HDFS-6313) WebHdfs may use the wrong NN when configured for multiple HA NNs
Date Sat, 10 May 2014 22:12:43 GMT

    [ https://issues.apache.org/jira/browse/HDFS-6313?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13993042#comment-13993042

Kihwal Lee commented on HDFS-6313:
----------------------------------

MiniDFSCluster or NN does not alter the config after its up. It was a easy way to get HA config
set up for the test.
