Subject Re: no log exists in JM and TM when updated to Flink 1.7
Date Thu, 03 Jan 2019 07:36:58 GMT
Hi Till

I found the root cause why log-not-show when use logback, because flink
does not include the logback-*.jar in the lib folder.
After I put the logback jar file in lib, everything is ok now.
I think flink should put the logback jar files into the lib directory, not
just the log4j jar file, because the both log configuration file exist in
conf directory.

Yours sincerely
Joshua
