Subject [jira] Commented: (HADOOP-4106) add time, permission and user attribute support to fuse-dfs
Date Wed, 17 Sep 2008 05:03:44 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-4106?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12631650#action_12631650
] 

Pete Wyckoff commented on HADOOP-4106:
--------------------------------------

bq. Does the fuse-dfs currently let me read/write files that I dont have permission to do
so?

Yes, it does unconditionally. So,  this patch will improve things. the only thing is you will
get an IO error rather than a correct error message saying you don't have permissions. So,
in that respect, this patch is an improvement.  Albeit, getting an IO error rather than a
permission error is a little weird. I guess the question is whether it's preferable to let
people see files unconditionally or get an IO error when they do??

I think getting 4108 committed by Friday isn't possible. 

An alternative would be to assume -EPERM when libhdfs gives an error, but that would be pretty
hacky.

> add:
> dfs_chown
> dfs_utime
> dfs_chmod
> Change open to have its own FS on writes (should we do this on reads too??) and use it
for writes and disconnect when closing the file
> Chane mkdir to open the FS itself and then close it
> also added comments for dfs_access (which needs FileSystem support/libhdfs support) and
I added the dfs_symlink and truncate since these 3 are the only 3 things left as far as functionality.
