sql-client 提交job 疑问

Hi,all

使用zeppelin提交sqljob的时候发现在 flink jobmanager 中首先会打印以下日志，
2021-07-26 15:54:36,929 [Thread-6575] INFO
 org.apache.hadoop.hdfs.protocol.datatransfer.sasl.SaslDataTransferClient
org.apache.hadoop.hdfs.protocol.datatransfer.sasl.SaslDataTransferClient.checkTrustAndSend(SaslDataTransferClient.java:239)
[] - SASL encryption trust check: localHostTrusted = false,
remoteHostTrusted = false

想请问这个是干什么用的呢？有时候会打印一分钟左右，然后才会出现一下日志
2021-07-26 15:54:37,526 [flink-akka.actor.default-dispatcher-1803] INFO
 org.apache.flink.runtime.dispatcher.StandaloneDispatcher
org.apache.flink.runtime.dispatcher.Dispatcher.submitJob(Dispatcher.java:300)
[] - Received JobGraph submission 0d329a174ee4d33600fe75b635631bee .

看源码这种也确实太耗时了

有什么办法避免没呢?
