Subject [jira] Commented: (HADOOP-3264) libhdfs does not provide permissions in API
Date Thu, 10 Jul 2008 23:56:31 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-3264?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12612698#action_12612698
] 

Pete Wyckoff commented on HADOOP-3264:
--------------------------------------

I like the latter methods as the APIs are better defined and called out, but I think the former
single method is more in the spirit of hadoop and having a smaller #of apis but with params
that can be extended.

But, I do think the latter 4 methods are a better defined API.  What happens when the pathinfo
struct changes and old code doesn't know to set some needed field but still compiles against
a newer version that's expecting that field. Unless the new code takes are to check the hdfsFileInfo
structure is properly set, things could go haywire. e.g., adding last accessed int which is
not set could result in last accessed being set to 1970.
