> If a user doesn't set "–input_path" option, the job will still be submitted.
> Here is my command to run the job:
> {code:java}
> yarn jar
> $HADOOP_BASE_DIR/home/share/hadoop/yarn/hadoop-yarn-submarine-3.2.0-SNAPSHOT.jar
> job run \
> -verbose \
> -wait_job_finish \
> --env DOCKER_JAVA_HOME=/usr/lib/jvm/java-8-oracle \
> --env DOCKER_HADOOP_HDFS_HOME=/hadoop-3.2.0-SNAPSHOT \
> --name tf-job-001 \
> --docker_image tangzhankun/tensorflow \
> --worker_resources memory=4G,vcores=2 \
> --worker_launch_cmd "cd /cifar10_estimator && python cifar10_main.py
> --data-dir=%input_path% --job-dir=%checkpoint_path% --num-gpus=0
> --train-steps=5"{code}
> Due to lack of invalidity check, the job is still submitted. We should add a
> check on this.
