我有一个shell脚本,它使用spark submit启动spark应用程序。
18/10/07 06:00:53 WARN SparkConf: In Spark 1.0 and later spark.local.dir will be overridden by the value set by the cluster manager (via SPARK_LOCAL_DIRS in mesos/standalone and LOCAL_DIRS in YARN).
18/10/07 06:00:53 WARN SparkConf: Detected deprecated memory fraction settings: [spark.shuffle.memoryFraction, spark.storage.memoryFraction, spark.storage.unrollFraction]. As of Spark 1.6, execution and storage memory management are unified. All memory fractions used in the old model are now deprecated and no longer read. If you wish to use the old memory management, you may explicitly enable `spark.memory.useLegacyMode` (not recommended).

从日志来看,启动某个服务器大约需要6分钟?

我会问这里会发生什么,为什么要花这么多时间?
