[jira] [Commented] (HADOOP-16291) HDFS Permissions Guide appears
incorrect about getFileStatus()/getFileInfo()
[ https://issues.apache.org/jira/browse/HADOOP-16291?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16832635#comment-16832635 ]
Daryn Sharp commented on HADOOP-16291:
--------------------------------------
Docs are correct. That's the HA state check, not a permissions check.

> Noticed this when reviewing HADOOP-16251. The FS Permissions [documentation|https://hadoop.apache.org/docs/r3.2.0/hadoop-project-dist/hadoop-hdfs/HdfsPermissionsGuide.html] seems to mark a lot of permissions as Not Applicable (N/A) when that is not the case. In particular getFileInfo (getFileStatus) checks READ permission bit [here|https://github.com/apache/hadoop/blob/trunk/hadoop-hdfs-project/hadoop-hdfs/src/main/java/org/apache/hadoop/hdfs/server/namenode/FSNamesystem.java#L3202-L3204], as it should.
