Subject [jira] [Commented] (HADOOP-8310) FileContext#checkPath should handle URIs with no port
Date Tue, 24 Apr 2012 18:15:38 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-8310?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13260773#comment-13260773

Daryn Sharp commented on HADOOP-8310:
-------------------------------------

{{AbstractFileSystem}} should use the same implementation as {{FileSystem}}.  This patch doesn't
appear to support canonicalization correctly.

> AbstractFileSystem#checkPath is used to verify that a given path is for the same file
system as represented by the AbstractFileSystem instance.
> The original intent of the code was to allow for no port to be provided in the checked
path, if the default port was being used by the AbstractFileSystem instance. However, before
performing port handling, AFS#checkPath compares the full URI authorities for equality. Since
the URI authority includes the port, the port handling code is never reached, and thus valid
paths may be erroneously considered invalid.
