Hi Just a quick idea. Also check ALL directories returned by hadoop classpath for any Avro related classes.
I was struggling trying to use avro-1.7.0 with CDH4 but made it work by using the -libjars option and making sure my classes are used BEFORE the standard classes. There's a config property (dont remember) to set for that. Note the above setting is for the task's classpath, to control the classpath of your driver class set HADOOOP_CLASSPATH=... and HADOOOP_USER_CLASSPATH_FIRST=true Alan Sent from my iPhone On Jul 15, 2012, at 3:59, "Jeremy Lewi" <[email protected]> wrote: > hi avro-users, > > I'm getting the following exception when using avro 1.6.1 with CDH4. > java.lang.NoSuchMethodError: > org.apache.avro.specific.SpecificData.deepCopy(Lorg/apache/avro/Schema;Ljava/lang/Object;)Ljava/lang/Object; > > The offending code is > GraphNodeData copy = (GraphNodeData) > SpecificData.get().deepCopy(data.getSchema(), data); > > where GraphNodeData is a class generated from my AVRO record. > > The code runs just fine on CDH3.
