I want to read a  small reference data file from a UDF.  How do I make use of the distributed cache  for this purpose ?

Take a look at the builtin UDF Bloom (you can see the code at https://issues.apache.org/jira/secure/attachment/12518116/HCATALOG-289-2.patch ) for an example of how to use the distributed cache from a UDF.

Hi Alan,

I am also curious to see how the distributed cache is used in a UDF.
However, the code you reference in the patch doesn't appear to contain
such an example.  What is the name of source file?

Thanks,

stan

Sorry, copy paste error.  Let's try that again:
