1、cdh安装是parcel包下载完毕卡在分配环节

查看agent.log一下错误；

MainThread agent        ERROR    Caught unexpected exception in main loop.
Traceback (most recent call last):

    return self._parse_alternatives(alt_name, out)
  File "/opt/cm-5.8.3/lib64/cmf/agent/build/env/lib/python2.7/site-packages/cmf-5.8.3-py2.7.egg/cmf/client_configs.py", line 444, in _parse_alternatives
    path, _, _, priority_str = line.rstrip().split(" ")
ValueError: too many values to unpack

解决方案是修改 /usr/lib64/cmf/agent/build/env/lib/python2.7/site-packages/cmf-5.10.0-py2.7.egg/cmf/client_configs.py 这个脚本的第444行。

for line in output.splitlines():
      if line.startswith("/"):
        if len(line.rstrip().split(" "))<=4:
          path, _, _, priority_str = line.rstrip().split(" ")

          # Ignore the alternative if it's not managed by CM.
          if CM_MAGIC_PREFIX not in os.path.basename(path):
            continue

          try:
            priority = int(priority_str)
          except ValueError:
            THROTTLED_LOG.info("Failed to parse %s: %s", name, line)

          key = ClientConfigKey(name, path)
          value = ClientConfigValue(priority, self._read_generation(path))
          ret[key] = value

        else:
          pass
    return ret

　　其实就是添加 if len(line.rstrip().split(" "))<=4: 和 else: pass；
