Pig does not allow loading resources with the same name
-------------------------------------------------------
Key: PIG-2203
URL: https://issues.apache.org/jira/browse/PIG-2203
Project: Pig
Issue Type: Bug
Components: impl
Affects Versions: 0.8.1
Reporter: Chetan
I am trying to load some resources in my UDF using
MyClass.getClassLoader().getResources("myResource"). I have a bunch of
different files called "myResource" which are scattered across my library
files. In a non-Pig invocation, the above method returns an Enumeration
containing all the resource files called "myResource". When I call this from a
UDF, I can see only that the returned Enumeration only contains a single
"myResource". It looks like Pig's JarManager is combining all the jar's in the
class path into a single jar and the last entry wins. This kind of code and
resource layout is used for loading resource bundles in i18n/l10n. In my
opinion, at the very least, Pig shouldn't merge out resource files without a
warning. Also why should jar files have to be merged like that? Can they not be
added to Hadoop's distributed cache individually?
