Subject [jira] Commented: (HADOOP-3264) libhdfs does not provide permissions in API
Date Thu, 17 Apr 2008 22:19:21 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-3264?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12590224#action_12590224

Craig Macdonald commented on HADOOP-3264:

For the set methods, what sort of methods should be designed?

Option 1: 

One method that takes a reference to a hdfsFileInfo struct and updates all details of the
path, or the details that are not null.

int hdfsSetPathInfo(hdfsFS fs, const char* path, hdfsFileInfo* pathinfo);

Option 2:

Various methods for setting various properties of a file. Of note, there is a 
hdfsSetReplication method already.

int hdfsSetPathOwner(hdfsFS fs, const char* path, char* owner);
int hdfsSetPathGroup(hdfsFS fs, const char* path, char* owner);
int hdfsSetPathPermissions(hdfsFS fs, const char* path, short permissions);

int hdfsSetPathLastMod(hdfsFS fs, const char* path, tTime newtime);
