whirr cdh install version control

How can we control the hadoop version being install on ec2 using whirr. I can see the we have the following two line is the config file

whirr.hadoop-install-function=install_cdh_hadoop whirr.hadoop-configure-function=configure_cdh_hadoop

but how do we control what version to install?

CDH3 or CDH4?

Also, MVR1 or MVR2?

Solution

  • This is how its done in 0.8.1 

    whirr.env.mapreduce_version=2   
whirr.env.repo=cdh4

    This goes into your properties file.
