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,
