Subject [jira] [Commented] (PIG-2760) resources added with a relative path are added to the JobXXXX jar file under their absolute path
Date Tue, 19 Jun 2012 08:14:43 GMT

    [ https://issues.apache.org/jira/browse/PIG-2760?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13396596#comment-13396596

Mathias Herberts commented on PIG-2760:
---------------------------------------

Converting a relative path to an absolute one may be an issue when accessing a resource in
a UDF using getResourceAsStream

Previously, if we used 'REGISTER foo/bar;' in a script, you could access 'bar' by calling
this.getClass().getClassLoader().getResourceAsStream('foo/bar'); in your UDF, and this would
work whatever directory the pig script is run from.

If converting the relative path to an absolute one (with no leading '/'), the argument to
getResourceAsStream will need to be dependent on the directory from which the pig script is
run, this kinds of defeat usability.

> When registering a local resource using a relative path, the resource is added to the
JobXXXX jar under its absolute path.
> If a pig script contains the following:
> REGISTER etc/foo;
> and is executed from a directory /PATH/TO/DIR, the JobXXXX jar file will contain the
following:
> /PATH/TO/DIR/etc/foo
> instead of
> etc/foo
> which was the previous behavior
