Ilya Bystrov updated HIVE-14787:
--------------------------------
Description:
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)}}
