Running Giraph job inside Java code

[Ahmet Emre Aladağ]

Hi,

How can we run a Giraph job inside the java code? Using the scheme below 
didn't work.

...

    GiraphJob giraphJob = new GiraphJob(giraphConf, "LinkRank2");
giraphJob.getInternalJob().setJarByClass(LinkRankComputation.class);
    giraphJob.run(true);

...

Error in Hadoop logs:

java.lang.RuntimeException: java.lang.RuntimeException: 
java.lang.ClassNotFoundException: 
org.apache.giraph.examples.LinkRank.LinkRankComputation
        at org.apache.hadoop.conf.Configuration.getClass(Configuration.java:881)

I'm setting $HADOOP_CLASSPATH to the folder with giraph, giraph-examples 
jars. But it can't find the computation class.
