spark-submit 报错 Initial job has not accepted any resources

spark-submit  报这样的错误

 WARN scheduler.TaskSchedulerImpl: Initial job has not accepted any resources; check your cluster UI to ensure that workers are registered and have sufficient resources

错误原因是内存缺少资源 我的虚拟机内存只有1g，所以spark-env.sh配置

export SPARK_WORKER_MEMORY=800m

但是在我执行spark-submit的时候没有加 --executor-memory参数，spark-submit默认提交任务的时候是1024m，如下图 就出现了上面的错误 解决办法是 spark-submit 后面加--executor-memory 512m就运行正常了
