hue的web界面无法切换用户问题

作者:互联网

一、问题描述

  在hue的web界面登录了超级管理员用户(admin),想要切换其他用户(hive),注销不成功(地址栏报错:hue 500 服务器错误,然后又自动登录到超级管理员账户admin)。无其他明显报错,错误日志摘要:

 'ascii' codec can't encode characters in position 0-1: ordinal not in range(128)

二、环境描述

  CM和CDH都是6.2.0版本,hue为4.3.0版本

三、错误日志

[01/Sep/2021 15:05:21 +0800] exception    ERROR    Internal Server Error: /accounts/logout/
Traceback (most recent call last):

    LOG.warn("Error closing Impala session: %s" % e)
UnicodeEncodeError: 'ascii' codec can't encode characters in position 0-1: ordinal not in range(128)

四、解决方法

  在/opt/cloudera/parcels/CDH/lib/hue/build/env/lib/python2.7/site-packages目录下创建sitecustomize.py文件,编辑内容如下:

#encoding=utf8
import sys
reload(sys)
sys.setdefaultencoding('utf8')

  配置完成后在CM平台重启hue服务。

  恢复正常登录。

五、总结

  因为当前系统的Python版本为Python 2.x,默认编码是ascii,注销过程中出现了无法解析的字符,解决方法是设置utf-8字符集。
