Hadoop Eclipse plugin

[#1]

I am getting below error while executing Simple mapreduce programme using eclipse 'mars'
Hadoop 2.6
ubuntu: 15.05 (hacked it and made it 14.04 to avaoid any compatibility issues with hadoop)
using hadoop­eclipse pluggin 2.6
Note that i am able to connect to HDFS via eclipse plugging since in the DFS location on right hand side i can
see the directory structure of HDFS.
Please find below the settings in eclipse and help to overcome the error while executing Mapreduce programme.
(Please note that if i make a jar out of the project via eclipse and run it in traditional command prompt way, i am
getting no issues(as the output and results are clearly visible in DFS location in eclipse, but i want to run it wia
eclipse as a whole))
Error while exeuting the programme :
