Subject Re: Can't list logs or stdout through web console on Flink 1.7 Kubernetes
Date Wed, 26 Dec 2018 10:33:04 GMT
wow, I met similar situation using flink 1.7 on yarn.

there was no jobmanager.log on the node but jobmanager.out and
jobmanager.error, and jobmanager.error contains the log message. so , there
was nothing in the webUI.

I do not know why this happened. by the way, I used logback to do log staff.
