I am new to Hadoop/Giraph and Java. As part of a task, I downloaded Cloudera Quickstart VM and Giraph on top of it. I am using this book named "Practical Graph Analytics with Apache Giraph; Authors: Shaposhnik, Roman, Martella, Claudio, Logothetis, Dionysios" from which I tried to run the first example on Page 111 (Twitter Followership Graph).
Defining the Shell Environment for Giraph Execution
$export HADOOP_HOME=/usr/lib/hadoop
$export GIRAPH_HOME=/usr/local/giraph
$export HADOOP_CONF_DIR=$GIRAPH_HOME/conf
$PATH=$HADOOP_HOME/bin:$GIRAPH_HOME/bin:$PATH
Running the Giraph Application
$ giraph target/*.jar GiraphHelloWorld -vip src/main/resources/1
-vif org.apache.giraph.io.formats.IntIntNullTextInputFormat
-w 1 -ca giraph.SplitMasterWorker=false,giraph.logLevel=error
I created both jar file and java program in /home/cloudera/target folder and the graph txt is created in src/main/resources/1.
I am facing the below attached error after running the above commands with the below attached program.
