> Currently nodemanager depends on bash shell. It should be well documented for system not having bash installed by default such as FreeBSD. Because only basic functionality of bash is used, probably changing bash to /bin/sh would work enough.
> i found 2 cases:
> 1. DefaultContainerExecutor.java creates file with /bin/bash hardcoded in writeLocalWrapperScript. (this needs bash in /bin)
> 2. yarn-hduser-nodemanager-ponto.amerinoc.com.log:2012-04-03 19:50:10,798 INFO org.apache.hadoop.yarn.server.nodemanager.DefaultContainerExecutor: launchContainer: [bash, -c, /tmp/nm-local-dir/usercache/hduser/appcache/application_1333474251533_0002/container_1333474251533_0002_01_000012/default_container_executor.sh]
> this created script is also launched by bash - bash anywhere in path works - in freebsd it is /usr/local/bin/bash
