>                 Key: HIVE-14787
>                 URL: https://issues.apache.org/jira/browse/HIVE-14787
>             Project: Hive
>          Issue Type: Bug
>          Components: Query Processor
>         Environment: 1.1.0+cdh5.7.1
>            Reporter: Ilya Bystrov

> I'm trying to create custom function
> {{create function geoip as 'some.package.UDFGeoIp' using jar 
> 'hdfs:///user/hive/ext/HiveGeoIP.jar', file 
> 'hdfs:///user/hive/ext/GeoIP.dat';}}
> According to https://issues.apache.org/jira/browse/HIVE-1016
> I should be able to access file via {{new File("./GeoIP.dat");}} (in 
> overridden method {{GenericUDF#evaluate(DeferredObject[] arguments)}})
> But this doesn't work.
> I use the following workaround, but it's ugly:
> {code}
> CodeSource codeSource = 
> GenericUDFGeoIP.class.getProtectionDomain().getCodeSource();
> File jarFile = new File(codeSource.getLocation().toURI().getPath());
> String jarDir = jarFile.getParentFile().getPath();
> File actualFile = new File(jarDir + "/GeoIP.dat");
> {code}
> UPDATE:
> It looks like I should use {{ClassLoader#getSystemResource(String resource)}}
