נושא: Re: UDF using third party jar

Hi,
it looks like jar version conflict - you might have two versions of jar 
containing class "net.sf.uadetector.UserAgentStringParser" on your classpath.

Hi

I am migrating my hive from CDH4 to CDH5(1.2),

I had a udf that extracts the useragent values out of the useragent string,

I am using the third-party uadetector library,

This UDF worked well in the CDH4

After the migration it stopped working because of:

Exception running child : java.lang.RuntimeException: 
java.lang.NoSuchMethodError:

In my code I am referring to the parse method of UserAgentStringParser, I add 
the jars required.

I also tried to override getRequiredJars, but the issue remains

Any idea?

Thanks,
