I’m new to java and trying to run a MR that uses HIPI: http://hipi.cs.virginia.edu/
I’ve used the command as described in:
http://hadoop.apache.org/common/docs/r0.20.2/mapred_tutorial.html
I’m using hadoop 0.20.2

my command looks like:
hadoop jar grayscalefromfile_exc.jar grayscalefromfile_exc.StubDriver -libjars hipi-0.0.1.jar imgs imgsOut1

where the path looks like:

 --
   --grayscalefromfile_exc.jar
   --hipi-0.0.1.jar

The error i get:
Exception in thread “main” java.lang.NoClassDefFoundError: hipi/imagebundle/mapreduce/ImageBundleInputFormat

Needless to say , the hipi-0.0.1.jar, has the path inside: hipi/imagebundle/mapreduce/ImageBundleInputFormat.java

Tnx

    libjars uploads the given jars to the cluster and then makes them available on the classpath for each mapper / reducer instance

    If you want to add additional jars to the driver client classpath, you’ll need to use the HADOOP_CLASSPATH env variable:

    #> export HADOOP_CLASSPATH=hipi-0.0.1.jar
#> hadoop jar grayscalefromfile_exc.jar grayscalefromfile_exc.StubDriver -libjars hipi-0.0.1.jar imgs imgsOut1

    And my output when i run this (the error relates to the fact i haven’t got a hipi image bundle file):

    cswhite@Studio-1555:~/workspace/sandbox/so-hipi/target$ export $HADOOP_CLASSPATH=/home/cswhite/Downloads/hipi-0.0.1.jar
cswhite@Studio-1555:~/workspace/sandbox/so-hipi/target$ echo $HADOOP_CLASSPATH
/home/cswhite/Downloads/hipi-0.0.1.jar
cswhite@Studio-1555:~/workspace/sandbox/so-hipi/target$ hadoop jar so-hipi-0.0.1-SNAPSHOT.jar StubDriver -libjars ~/Downloads/hipi-0.0.1.jar images output
