CDH集群impala报错:角色无法启动,Invalid short-circuit reads configuration:

博主最近在安装CDH的时候,发现每次安装都跟逛海南之家一样,每次都有新问题。

这次的impala又出问题了,重装了agent还是有问题,发现这个办法可以,分析一下。

1.安装cdh集群时候,有一台节点impala莫名起不来,报错

 2.点进去查看日志提示:

Invalid short-circuit reads configuration:

- Impala cannot read or execute the parent directory of dfs.domain.socket.path Aborting Impala Server startup due to improper configuration. Impalad exiting.

 3.解决方法:

先进入web页面,查看HDFS一个路径:dfs.domain.socket.path

HDFS-配置-搜索dfs.domain.socket.path

远程出错的服务器,查看是否新建了这个文件夹

ll /var/run/hdfs-sockets/dn

 新建文件夹,并授权

mkdir -pv /var/run/hdfs-sockets/dn

chmod 777 hdfs-sockets

回到web界面重启impala

4.重启后ok
