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 : Picked up JAVA_TOOL_OPTIONS: ­javaagent:/usr/share/java/jayatanaag.jar 2016­01­08 07:32:46,255 INFO [main] datanode.DataNode (StringUtils.java:startupShutdownMessage(633)) ­ STARTUP_MSG: /************************************************************ ..... ... ..
