You need to use import by name instead of import
by location in your descriptor. Then things get
loaded via the classpath and you should be ok
(provided that you stick your descriptors in the
jar of course). I suggest you test this locally
first by moving your application to a different
machine where you don't have any descriptors
lying around. It'll be easier to debug than in
hadoop.

Well the question is for running UIMA over hadoop? How to do that as in UIMA
there are xml descriptors which have relative urls and location? Which
throws exception
But I can probably do without that answer
Simplifying the problem
I create a jar for my application and I am trying to run a map reduce job
In the map I am trying to read an xml resource which gives this kind of
exceprion
java.io.FileNotFoundException:

I think I require to pass on the content of the jar which contains the
resource xml and classes(other than the JOB class) to each and every
taskXXXXXXX getting created
How can I do that

Hi
A simple thing such as a name annotator which has an import location of
type starts throwing exception when I create a jar of the application I
am
developing and run over hadoop.
If I have to do it a java class file then I can use XMLInputSource in =
new
XMLInputSource(ClassLoader.getSystemResourceAsStream(aeXmlDescriptor),null);
But the relative paths in annotators, analysis engines etc starts
throwing
exception
Please Help

I'm not sure I understand your question, but I think you need some help
with the exceptions you get.
Can you provide the exception stack trace?
