Graham Gear commented on WHIRR-677:
-----------------------------------

Thanks for raising this and good job getting to the bottom of the issue.

A recent patch committed against WHIRR-675 will resolve this, so from 0.8.2 onwards you will not have to upper case the whirr.env variables and issues like this will not eventuate.

> Whirr fails to install yarn-nodemanager on designated machines. It creates a yarn-nodemanager service and attempts to start it but it fails as it cannot find /usr/lib/hadoop-mapreduce folder. This folder is installed as part of YARN mapreduce. It installs hadoop-mapreduce-0.20. 
> The problems seems to come from property files. Even after specifying 
> whirr.env.mapreduce_version=2
> It fails to install hadoop-mapreduce. On some investigation i found that this variable needs to be converted to UPPER CASE as all other variable in subsequent scripts. 
> If i put 
> whirr.env.MAPREDUCE_VERSION=2
> it works. 
> Someone please take a not and correct this.
