1、 启动yarn,resourceManger启动失败，日志报错：
org.apache.hadoop.yarn.exceptions.YarnRuntimeException: java.net.BindException: Problem binding to [jx-vm04:8031] java.net.BindException: Cannot assign requested address; For more details see: http://wiki.apache.org/hadoop/BindException
定位：
1、netstat –ano | grep '8031' 查不到端口占用；
2、可能是yarn-site.xml配置异常，查看配置信息：
<configuration>
<!-- Site specific YARN configuration properties -->
<!-- 1、指定YARN的老大（ResourceManager）的地址 -->
<property> <name>yarn.resourcemanager.hostname</name> <value>jx-vm04</value> </property> <!-- 2、reducer获取数据的方式 --> <property> <name>yarn.nodemanager.aux-services</name> <value>mapreduce_shuffle</value> </property> </configuration> 信息配置正常； 3、查看主机配置文件： $ cat /etc/hosts 127.0.0.1 localhost #127.0.1.1 jx-vm04 10.10.75.15 jx-vm04 192.168.120.159 mc.zk.thinkjoy.cn #10.10.75.16 jx-vm01 192.168.3.16 sd-hjy-vm02 本地主机名配置成映射的外网IP（10.10.75.15），这里要使用内网IP地址才行 改成： 127.0.1.1 jx-vm04 或者 192.168.3.15 jx-vm04 改完保存，重启 start-yarn.sh 查看结果： /hadoop/hadoop-2.4.1/etc/hadoop$ jps 14338 NameNode 25379 NodeManager 25901 ResourceManager 14468 DataNode 26302 Jps 14666 SecondaryNameNode 启动成功。2、配置单机版hbase，启动后报错：
hadoop@jx-vm04:/usr/local/wangpei/cloud/hbase/hbase-0.98.24-hadoop2/bin$ ./start-hbase.sh starting master, logging to /usr/local/wangpei/cloud/hbase/hbase-0.98.24-hadoop2/bin/../logs/hbase-hadoop-master-jx-vm04.out /usr/local/wangpei/cloud/hbase/hbase-0.98.24-hadoop2/bin/hbase-daemon.sh: 行 189: /usr/local/wangpei/cloud/hbase/hbase-0.98.24-hadoop2/bin/../logs/hbase-hadoop-master-jx-vm04.out: 权限不够 head: 无法打开"/usr/local/wangpei/cloud/hbase/hbase-0.98.24-hadoop2/bin/../logs/hbase-hadoop-master-jx-vm04.out" 读取数据: 没有那个文件或目录 hadoop@jx-vm04:/usr/local/wangpei/cloud/hbase/hbase-0.98.24-hadoop2/bin$ sudo ./start-hbase.sh starting master, logging to /usr/local/wangpei/cloud/hbase/hbase-0.98.24-hadoop2/bin/../logs/hbase-root-master-jx-vm04.out Could not start ZK at requested port of 2181. ZK was started at port: -1. Aborting as clients (e.g. shell) will not be able to find this ZK quorum.可以看到在默认账户下提示权限不够，说明要使用管理员账号或者对应安装的权限账号，因为hbase是在hadoop账户下安装的，而zk是在默认的ubuntu账户下安装的，2181端口被ubuntu下的zk占用，而hbase无权访问。
解决办法：
将sudo下的zk服务占用进程杀掉，在hadoop账户下启动zk：
hadoop@jx-vm04:/usr/local/wangpei/cloud/zookeeper/zookeeper-3.4.6/bin$ ./zkServer.sh
JMX enabled by default
启动hbase：
./start-hbase.sh
starting master, logging to /usr/local/wangpei/cloud/hbase/hbase-0.98.24-hadoop2/bin/../logs/hbase-root-master-jx-vm04.out
hbase单机启动成功：
hadoop@jx-vm04:/usr/local/wangpei/cloud/hbase/hbase-0.98.24-hadoop2/bin$ ps -ef | grep hbase
