我在Spark 1.5中遇到以下错误：
Diagnostics: Container [pid=19554,containerID=container_e94_1518800506024_42837_02_000017] is running beyond physical memory limits. Current usage: 3.5 GB of 3.5 GB physical memory used; 4.3 GB of 7.3 GB virtual memory used. Killing container. Dump of the process-tree for container_e94_1518800506024_42837_02_000017
MASTER_URL =纱簇
NUM_EXECUTORS = 10
EXECUTOR_MEMORY = 4G
EXECUTOR_CORES = 6
DRIVER_MEMORY = 3G
应用程序读取的数据是7MB的avro文件，但在spark应用程序中有多次写入。
作业配置有问题吗？
