Hi ,
>From the flink doc , in order to use logback instead of log4j " Users
willing to use logback instead of log4j can just exclude log4j (or delete
it from the lib/ folder)."
https://ci.apache.org/projects/flink/flink-docs-stable/monitoring/logging.html
.
However when i delete it from the lib and start the cluster , there are no
logs generated , instead I see console log which says "Failed to
instantiate SLF4J LoggerFactory"
Reported exception:
java.lang.NoClassDefFoundError: org/apache/log4j/Level
at org.slf4j.LoggerFactory.bind(LoggerFactory.java:143)
at org.slf4j.LoggerFactory.performInitialization(LoggerFactory.java:122)

at org.slf4j.LoggerFactory.getLogger(LoggerFactory.java:349)
at
org.apache.flink.runtime.entrypoint.ClusterEntrypoint.<clinit>(ClusterEntrypoint.java:98)
How can I use logback instead ?
Thanks,
Vishwas
