问题重现

测试环境

1.Redhat7.4

2.CDH6.1.1

Fayson在前面《0635-5.16.1-Hue集成HBase出现Api Error异常分析》文章中说明了在C5中Hue与HBase集成问题，本篇文章主要分析C6环境下进行异常。

1.登录Hue进入HBase模块异常显示如下

2.查看Hue服务的日志有如下报错信息

异常分析

1.通过查看Hue的配置文件hue.ini看到HBase的配置模块有如下信息

代码语言：javascript复制

# Should come from hbase-site.xml, do not set. 'framed' is used to chunk up responses, used with the nonblocking server in Thrift but is not supported in Hue.
  # 'buffered' used to be the default of the HBase Thrift Server. Default is buffered when not set in hbase-site.xml.
  ## thrift_transport=buffered
