Hi Vitaliy Property of 'log.file' would be configured if you have uploaded 'logback.xml' or 'log4j.properties' [1]. The file would contain logs of job manager or task manager which is decided by the component itself. And as you can see, this is only a local file path, I am afraid this cannot understand hdfs paths.

Hi, When I launch Flink Application Cluster I keep getting a message " Log file environment variable 'log.file' is not set." I use console logging via log4j and I read logs via yarn logs -applicationId .... What's the purpose of log.file property? What this file will contain and on which host should I search for the log? Does this property understands hdfs paths? Regards, Vitaliy
