Description

when use fetchAllConnections(), Sometimes it doesn't work。

datanode throws  TProtocolException: Required field 'userName' was not present! Struct: TSConnectionInfo(userName:null, logInTime:0, connectionId:172.20.31.19:57584, type:THRIFT_BASED). 

Under what circumstances does this problem occur。

Sometimes the field 'userName'  maybe empty 

branch：rel/1.0、rel/1.1、master

------

fetchAllConnections方法有时候无法正常返回连接信息。

查看服务器出现如下日志。不确定什么情况下会出现该问题，但是经常会出现。

看日志是某些连接 'userName' 为空导致的，可能是建立了thrift连接但没有正常使用？

影响分支：rel/1.0、rel/1.1、master
