[jira] [Commented] (HADOOP-3257) Path should handle all characters

["Daryn Sharp (Commented) (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HADOOP-3257?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13230286#comment-13230286 ] 

Daryn Sharp commented on HADOOP-3257:
-------------------------------------

Per the bug that got dupped to this one, : could be handled correctly if the RFC for URI syntax is more closely followed for scheme & authority.
* Path looks for a : and / and checks that the colon occurs before the /.  It really should be colon_index = slash_index - 1.  
* There's a limited number of chars valid in a scheme.  Path should stop looking for a : if a non-valid scheme char is encountered.

That would take care of most cases.  Now let's say someone _really_ does want a relative path that looks like a URI, ex. {{foo:/bar}}.  They can use {{./foo:/bar}} to disambiguate.

I have a heap of un-submitted patches littering my home/work laptop, and one that implements this behavior is lying around somewhere...

> Currently Path is limited by URI semantics in the sense that one cannot create files whose names include characters such as ":" etc.
> HADOOP-2066 & HADOOP-3256 are manifestations of this problem. It would be nice if Path handled all characters correctly...
