Subject: Running giraph custom code on CDH5.1.0
To: user <user@giraph.apache.org>


Hi,
  So, I have Hadoop 2.3.0-cdh5.1.0 installed on my cluster... and I
compiled giraph thru the following command.. mvn clean package -DskipTests
-Dhadoop=non_secure -Phadoop_2.0.0
So, the compilation worked just fine and then the pagerank benchmark also
succeeded..
So, I am guessing giraph compiled just fine..


Now, I am trying to run my code..
hadoop jar graphAnalytics-0.0.1-SNAPSHOT-jar-with-dependencies.jar
org.apache.giraph.GiraphRunner
 -Dgiraph.zkList=srv-110-07:2181,srv-110-08:2181,srv-210-08:2181
org.examples.graphAnalytics.PageRankVertex -w 1 -vif
org.examples.graphAnalytics.PageRankInputFormat

And I am getting this error:
Exception in thread "main" java.lang.IncompatibleClassChangeError: Found
interface org.apache.hadoop.mapreduce.JobContext, but class was expected
 at
org.apache.giraph.bsp.BspOutputFormat.checkOutputSpecs(BspOutputFormat.java:43)

I know, its an incomplete command but its already complaining.. :-/
