CDH5.4.0安装时遇到的问题



1.   问题：yarn启动报错，报错内容为   ValueError: dictionary update sequence element #86 has length 1; 2 is required

      解决办法：

修改  cm-5.1.3/lib64/cmf/agent/src/cmf/util.py文件

pipe = subprocess.Popen(['/bin/bash', '-c', ". %s; %s; env" % (path, command)],
改为
pipe = subprocess.Popen(['/bin/bash', '-c', ". %s; %s; env | grep =" % (path, command)],

即可正常启动yarn
