Description

Actions Performed

1. As advised by Hadoop exported JAVA_HOME=/cygwin/jdk1.2.7_40/bin in hadoop-env.sh and tried to run java commands with error
jar /cygwin/hadoop-1.2.1/hadoop-examples-1.2.1.jar
-bash: jar: command not found
2. However when echoed I get right pointed path
echo $JAVA_HOME
/cygwin/jdk1.7.0_40/bin
3. Tried including export path in .bash_profile, and .profile, with same error.

Unable to move forward with out JDK calls. Anticipate the same with Hadoop related commands.
