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?
