Hi， Austin， It’s good to have this instruction. But I still have some problem. when I start the cluster, it says I have problems with yarn-site.xml
16/10/31 18:21:04 FATAL conf.Configuration: error parsing conf yarn-site.xml
org.xml.sax.SAXParseException; systemId: file:/usr/local/hadoop/etc/hadoop/yarn-site.xml; lineNumber: 31; columnNumber: 3; The markup in the document following the root element must be well-formed.
