Hi All,
I'm new to Giraph and I'm having some difficulties getting it to run with
Hive on Hadoop2. This is the error message that I am getting:
Exception in thread "main" java.lang.IncompatibleClassChangeError: Found
interface org.apache.hadoop.mapreduce.JobContext, but class was expected

Here is the command that I am running:
$HIVE_HOME/bin/hive --service jar
/usr/local/giraph/giraph-hive/target/giraph-hive-1.1.0-jar-with-dependencies.jar
org.apache.giraph.hive.jython.HiveJythonRunner -hiveconf
giraph.SplitMasterWorker=false
/usr/local/giraph/giraph-core/src/test/resources/org/apache/giraph/jython/count-edges.py
/usr/local/giraph/giraph-hive/src/test/resources/org/apache/giraph/jython/count-edges-launcher.py
These are the specific versions that I'm running:
Hadoop: 2.7.1
Hive: 1.2.1
Giraph: 1.1.0
I built Giraph using this command:
mvn -Phadoop_2 -fae -DskipTests clean install
It seems to me that the error is caused by HiveIO being built against
Hadoop1, but I can't find any instructions on how to build it for Hadoop2.
I also saw an email in the mailing list archives where someone had the same
error, but I didn't see a resolution in the thread. Does anyone have any
thoughts on what I can do to move past this error?
Thanks,
Steve
