我有一个奇怪的问题。我被困了一个星期来解决它，但不幸的是找不到解决方法。
我正在使用Spark 2.3.0。我可以在远程（ssh）对其进行访问的Linux服务器上使用该版本。
要运行我的应用程序（test.py），请编写以下脚本：
#!/bin/bash
#SBATCH --account=def-moudi
#SBATCH --nodes=2
#SBATCH --time=00:10:00
#SBATCH --mem=100G
#SBATCH --cpus-per-task=5
#SBATCH --ntasks-per-node=6
#SBATCH --output=/project/6008168/moudi/job/spark-job/sparkjob-%j.out
#SBATCH --mail-type=ALL
#SBATCH --error=/project/6008168/moudi/job/spark-job/error6_hours.out
# load the Spark module
module load spark/2.3.0
module load python/3.7.0
source "/home/moudi/ENV3.7.0/bin/activate"
# identify the Spark cluster with the Slurm jobid
export SPARK_IDENT_STRING=$SLURM_JOBID
export JOB_HOME="$HOME/.spark/2.3.0/$SPARK_IDENT_STRING"
mkdir -p $JOB_HOME
## --------------------------------------
## 1. Start the Spark cluster master
## --------------------------------------
$SPARK_HOME/sbin/start-master.sh
sleep 5
MASTER_URL=$(grep -Po '(?=spark://).*'
$SPARK_LOG_DIR/spark-${SPARK_IDENT_STRING}-org.apache.spark.deploy.master*.out)
## --------------------------------------
## 2. Start the Spark cluster workers
## --------------------------------------
# get the resource details from the Slurm job
export SPARK_WORKER_CORES=${SLURM_CPUS_PER_TASK:-1}
export SPARK_MEM=$(( ${SLURM_MEM_PER_CPU:-3072} * ${SLURM_CPUS_PER_TASK:-1} ))
export SPARK_DAEMON_MEMORY=${SPARK_MEM}m
export SPARK_WORKER_MEMORY=${SPARK_MEM}m
NWORKERS=${SLURM_NTASKS:-1} #just for testing you should delete this line
# start the workers on each node allocated to the job
export SPARK_NO_DAEMONIZE=1
srun -n ${NWORKERS} -N $SLURM_JOB_NUM_NODES --label -- output=$SPARK_LOG_DIR/spark-%j-workers.out start-slave.sh -m ${SPARK_MEM}m -c
${SPARK_WORKER_CORES} ${MASTER_URL} &
## --------------------------------------
## 3. Submit a task to the Spark cluster
## --------------------------------------
spark-submit --master ${MASTER_URL} --total-executor-cores $((SLURM_NTASKS *
SLURM_CPUS_PER_TASK)) --executor-memory ${SPARK_WORKER_MEMORY} --driver-memory ${SPARK_WORKER_MEMORY}m --num- executors $((SLURM_NTASKS - 1)) /project/6008168/moudi/test.py
## --------------------------------------
## 4. Clean up
## --------------------------------------
# stop the workers
scancel ${SLURM_JOBID}.0
# stop the master
$SPARK_HOME/sbin/stop-master.sh
运行该脚本时，我注意到只有8个工人不正确，因为应该是11个工人？ worker输出的日志文件如下：
