Subject [jira] Commented: (HADOOP-6427) Add Path isQualified
Date Tue, 22 Dec 2009 18:58:29 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-6427?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12793731#action_12793731
] 

Sanjay Radia commented on HADOOP-6427:
--------------------------------------

Absolute paths:
Agree with Eli's comment on absolute links. It is consistent with the "symlinks are resolved
relative to their source" is consistent with 
"volume root relative". I was thrown off by Doug's comment in HDFS-245 where he said "Links
should be resolved against the client's context."; this seems to be in conflict with his "symlinks
are resolved relative to their source".
Also thanks for the "hdfs://host1/dir/foo" I had missed that case. I agree with your analysis.

Partially qualified syntax (The partially qualified syntax (a scheme but no host, eg hdfs:///foo)).
I agree that the syntax is goofy if the scheme is ignored. Not sure if everyone will buy into
the "%" syntax (it was inspired by the "~" syntax but such 
special character get messy after a while.) Can we use a special scheme such as "clientContext:///foo"?
So is your proposal to mark partially qualified syntax as invalid or to allow them with the
somewhat "goofy" interpretation.

> The Path class has a method to make a path qualified but not to query if the path is
qualified. This is needed for HADOOP-64221. In addition this patch adds tests to TestPath
that cover the file scheme. Note that "fully qualified" applies to domain names not URIs so
this function and it tests also serve to define what we mean by a fully qualified path.
