> If you start a pseudo distributed yarn using "start-yarn.sh" you need to
> specify exports for HADOOP_COMMON_HOME, HADOOP_HDFS_HOME, YARN_HOME,
> YARN_CONF_DIR, and HADOOP_MAPRED_HOME in hadoop-env.sh (or elsewhere),
> otherwise the spawned node manager will be missing these in it's environment.
> This is due to start-yarn using yarn-daemons. With this fix it's possible to
> start yarn (etc...) with only HADOOP_CONF_DIR specified in the environment.
> Took some time to track down this failure, so seems worthwhile to fix.
