Subject Re: flink can't read hdfs namenode logical url
Date Mon, 23 Oct 2017 07:17:26 GMT
Hi,

Why in this new message there is a different host? Previously code was trying to connect to
“master:8020” and now it is “startdt”? If you were able to change this host somehow
between runs, I guess you should be also able to set it to correct one.
