大叔经验分享（53）kudu报错unable to find SASL plugin: PLAIN

kudu安装后运行不正常，master中找不到任何tserver，查看tserver日志发现有很多报错：

Failed to heartbeat to master:7051: Invalid argument: Failed to ping master at master:7051: Client connection negotiation failed: client connection to master:7051: unable to find SASL plugin: PLAIN

解决方法：

yum install gcc python-devel
yum install cyrus-sasl*

然后重启kudu，如果还有impala，也需要重启；
