Mr. Roland: This is what I get. How do I now get Oracle JDK to be identified anand_vihar@Latitude-E5540:~$ sudo update-alternatives --config java [sudo] password for anand_vihar: There is only one alternative in link group java (providing /usr/bin/java): /usr/lib/jvm/java-7-openjdk-amd64/jre/bin/java Nothing to configure.

For Ubuntu, try sudo update-alternatives --config java.

I have the extracted version of the Oracle JDK7. However I am ignorant regarding its installation on Ubuntu. Can you point me to installation material so that I can look up and try.

At a prompt, as su, run the command ‘alternatives - - config java’. Make sure that the oracle version is listed and is marked as the active one. If it is not, go through the steps to make sure it is. - rd From: Anand Murali [mailto:anand_vi...@yahoo.com] Sent: Wednesday, April 01, 2015 5:42 AM To: user@hadoop.apache.org Subject: Re: Hadoop 2.6 issue I continue to get the samede error.I export JAVA_HOME=/home/anand_vihar/jdk1.0.7_u75 (in hadoop-env.sh) when I echo $JAVA_HOME it shows me the above path but when I $java -version, it gives me openjdk version start-dfs.sh ....... errors out saying JAVA_HOME not set., but echo shows JAVA_HOME.
