Thanks@Ali Bajwa and @Artem Ervits. I tried Ali's suggestion and it still shows that Java 1.7 when i do Java -version. But, i got a different error when I ran the mapred program in the terminal. Now it says that i don't have the write access on the file/directory i am trying to write. I need to check that. When i run the same in Hue, i get a message that 'Output directory not set in JobConf.' I am researching on this error now.

I am new to Hadoop and started learning it, but have some beginners problems with the setup. I had HDP 2.2 with JDK 1.7 and i tried to execute map reduce coded with 1.8. And i realized that HDP 2.2 does not support JDK 1.8 and i have upgraded it to HDP 2.3. When i execute Java -Version, i am still getting Java 1.7. As per the directions in HDP, i have used ambari-server setup to download JDK 1.8 and even after that Java -version is showing 1.7. How to make it use JDK 1.8 as the default?
