Subject [jira] [Commented] (HADOOP-8101) Security changes for Hadoop for Windows
Date Fri, 02 Mar 2012 00:24:59 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-8101?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13220531#comment-13220531
] 

Sanjay Radia commented on HADOOP-8101:
--------------------------------------

* src/core/org/apache/hadoop/fs/RawLocalFileSystem.java
Why set the status (U,G, etc) to null – don’t you want the actual permission for the user,
group and world. There is no concept of groups in widows and elsewhere you have used a group
called "Users".
* src/core/org/apache/hadoop/io/SecureIOUtils.java
if RawLocalFile is fixed then you will not need this.
* src/core/org/apache/hadoop/security/UserGroupInformation.java
** newLoginContext() Patch screwed up – you must have accidently picked up the change from
HADOOP-7982
** getCurrentUser() – the existing code should work - should not need a WINDOWS-os check
* src/core/org/apache/hadoop/security/ShellBasedUnixGroupsMapping.java
The right way is to use a java class to get the windows group and make the default windows
config point to this class for getting group mappings. If this is the only place where we
have a need for different default config for windows I could live with the patch.
* src/core/org/apache/hadoop/security/Credentials.java
Job tokens are set for both secure and non-secure. This change should not be needed. Did things
break without this change?
