I am running an example mapreduce job that comes with Hadoop 2.8.1
I am using these commands:
bin/hdfs dfs -copyFromLocal etc/hadoop/core-site.xml .
bin/hadoop jar share/hadoop/mapreduce/hadoop-mapreduce-examples-2.7.3.jar grep ./core-site.xml output ‘configuration’
However, when I run this, the job exits (the main error appears in the title):
***********s-mbp-2:hadoop-2.8.1 ***********$ bin/hadoop jar share/hadoop/mapreduce/hadoop-mapreduce-examples-2.8.1.jar grep ./core-site.xml output ‘configuration’
