Zhankun Tang created YARN-8799:
----------------------------------
Summary: [Submarine] A default directory path in HDFS for
"checkout_path"?
Key: YARN-8799
URL: https://issues.apache.org/jira/browse/YARN-8799
Project: Hadoop YARN
Issue Type: Sub-task
Reporter: Zhankun Tang
Assignee: Zhankun Tang
Fix For: 3.2.0
It might be more simple for user to use "--checkout_path" if we provide a
default path in HDFS for checkout_path. It could be under current staging dir
or other place that make sense.
{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 \
-keep_staging_dir \
--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 \
--input_path hdfs://default/user/yarn/cifar-10-data \
--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}
Above script should works, but the job failed due to invalid path passed to
"--job-dir" per my testing. It should be a URI start with "hdfs://".
