Hi,
       信息如下：

    Log Type: jobmanager.err
Log Upload Time: 星期五 十月 15 12:47:03 +0800 2021
Log Length: 247
log4j:WARN No appenders could be found for logger 
(org.apache.flink.runtime.entrypoint.ClusterEntrypoint).
log4j:WARN Please initialize the log4j system properly.
log4j:WARN See http://logging.apache.org/log4j/1.2/faq.html#noconfig for more

怎么去定位该问题呢？
