如何启动ResourceManager和NodeManager

1. 登录到bigtop1上，vagrant ssh bigtop1

将/usr/lib/hadoop/libexec/init-hdfs.sh文件内容替换为:

### Script requires package bigtop-groovy to be installed
# Use this script to initialize HDFS directory structure for various components
# to run. This script can be run from any node in the Hadoop cluster but should
# only be run once by one node only. If you are planning on using oozie, we
# recommend that you run this script from a node that has hive, pig, sqoop, etc.
# installed. Unless you are using psuedo distributed cluster, this node is most
# likely NOT your namenode
# Steps to be performed before running this script:
# 1. Stop the namenode and datanode services if running.
# 2. Format namenode (su -s /bin/bash hdfs hdfs namenode -format).
# 3. Start the namenode and datanode services on appropriate nodes.

# Autodetect JAVA_HOME if not defined
if [ -f /usr/lib/bigtop-utils/bigtop-detect-javahome ]; then
  . /usr/lib/bigtop-utils/bigtop-detect-javahome

在bigtop1上执行命令：

puppet apply -d --modulepath=/bigtop-home/bigtop-deploy/puppet/modules:/etc/puppet/modules:/usr/share/puppet/modules /bigtop-home/bigtop-deploy/puppet/manifests/site.pp

执行完后，使用jps命令查看：
