Hi,

I’m currently playing a little with hdfs and yarn (Hadoop 2.7.1) on my laptop (Darwin Kernel Version 14.5.0 / OS X Yosemite Version 10.10.5) . Until then, I was mainly doing HBase development and I thought it could be nice if I learn some basic stuff such as Map Reduce programming before starting with Spark.

While I was trying the Map Reduce tutorial, I fall on this error:

15/08/17 22:59:29 INFO mapreduce.Job: Job job_1439843536878_0001 failed with state FAILED due to: Application application_1439843536878_0001 failed 2 times due to AM Container for appattempt_1439843536878_0001_000002 exited with  exitCode: 127

For more detailed output, check application tracking page:http://MacBook-Pro-de-Pierre.local:8088/cluster/app/application_1439843536878_0001Then, click on links to logs of each attempt.

Failing this attempt. Failing the application.

15/08/17 22:59:29 INFO mapreduce.Job: Counters: 0

This simple command fix the issue:

sudo ln -s /usr/bin/java /bin/java

Hope this helps.
