解决办法：
看到ClouderaManager启动NodeManager失败，读取的配置文件是/etc/hadoop/conf.cloudera.yarn/container-executor.cfg，这个文件为空。
参考/module/cloudera/parcels/CDH-5.4.0-1.cdh5.4.0.p0.27/etc/hadoop/conf.empty/container-executor.cfg配置文件，将对应信息写入到/etc/hadoop/conf.cloudera.yarn/container-executor.cfg文件中，问题解决。
echo "yarn.nodemanager.linux-container-executor.group=yarn" > /etc/hadoop/conf.cloudera.yarn/container-executor.cfg
还没有发现副作用，发现再更新。
