Description

The various yarn shell scripts assume that JAVA_HOME, HADOOP_COMMON_HOME, YARN_CONFIG_DIR etc are all in directories without spaces. This likely to break on windows, where JAVA_HOME is often C:\Program Files\Java

They all need reviewing, and ideally testing on a machine that has everything installed into directories with spaces.
