I need to be able to use Java 8 in EMR I have found this post
https://crazydoc1.wordpress.com/2015/08/23/java-8-on-amazon-emr-ami-4-0-0/
Which provides a bootstrap shell script
https://gist.github.com/pstorch/c217d8324c4133a003c4
Which installs java 8.
When looking at documentation on how to use bootstrap scripts its not apparent at all how to use a shell script with bootstrap actions since in documentation it asks for a Jar location (https://docs.aws.amazon.com/ElasticMapReduce/latest/ManagementGuide/emr-plan-bootstrap.html)
Under Bootstrap Actions select Configure and add to specify the Name, JAR location, and arguments for your bootstrap action. Choose Add.
I don't have a Jar location I have a shell script as a bootstrap action.
How am I suppose to use a shell script should I just enter the shell script as Jar location?
回答1:
Yes, all you have to do is add the S3 location of your script as the JAR location (or just navigate to it using the form).
Example:
s3://mybucket/myfolder/myscript.sh
