[jira] [Commented] (HDFS-10436) dfs.block.access.token.enable
should default on when security is !simple
[ https://issues.apache.org/jira/browse/HDFS-10436?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15352958#comment-15352958 ]
Allen Wittenauer commented on HDFS-10436:
-----------------------------------------
Oh, so if block token access is enabled on an insecure cluster, it doesn't actually do anything? If so, then let's add that to description in hdfs-site.xml so that admins understand why this is default to true.
