Again incompatibility, locating example jars

Hi,There is another incompatibility between 1.2.0 and 2.2.6. I appreciate is someone help to figure it out.This command works on 1.2.0
time ${HADOOP_HOME}/bin/hadoop jar  ${HADOOP_HOME}/hadoop-examples-*.jar grep ${WORK_DIR}/data-MicroBenchmarks/in ${WORK_DIR}/data-MicroBenchmarks/out/grep a*xyz 
But on 2.6.0, I receive this error:
Not a valid JAR: /home/mahmood/bigdatabench/apache/hadoop-2.6.0/hadoop-examples-*.jar

Indeed there is no such file in that folder. So I guess it has been moved to another folder. However, there are three jar files in 2.6.0
/home/mahmood/bigdatabench/apache/hadoop-2.6.0/share/hadoop/mapreduce/sources/hadoop-mapreduce-examples-2.6.0-sources.jar
/home/mahmood/bigdatabench/apache/hadoop-2.6.0/share/hadoop/mapreduce/sources/hadoop-mapreduce-examples-2.6.0-test-sources.jar
/home/mahmood/bigdatabench/apache/hadoop-2.6.0/share/hadoop/mapreduce/hadoop-mapreduce-examples-2.6.0.jar


Which one should I use?

Regards,
Mahmood
