本文是一份开箱即用的全自动测试脚本，用于在 EMR Serverless 上提交一个 Delta Lake 作业。本文完全遵循《最佳实践：如何优雅地提交一个 Amazon EMR Serverless 作业？》一文给出的标准和规范！

1. 导出环境相关变量

注意：以下仅为示意值，实操时请根据个人环境替换相关值。

export APP_NAME="emr-serverless-deltalake-test"
export APP_S3_HOME="s3://$APP_NAME"
export APP_LOCAL_HOME="/home/ec2-user/$APP_NAME"
export EMR_SERVERLESS_APP_ID='00fbfel40ee59k09'
export EMR_SERVERLESS_EXECUTION_ROLE_ARN='arn:aws:iam::1111111111111:role/EMR_SERVERLESS_ADMIN'

2. 创建作业专属工作目录和S3存储桶

mkdir -p $APP_LOCAL_HOME
aws s3 mb $APP_S3_HOME

3. 准备作业脚本

cat << EOF >> $APP_LOCAL_HOME/delta_table.py
from datetime import datetime
from pyspark import SparkConf, SparkContext
from pyspark.sql import HiveContext, SparkSessionspark = SparkSession\.builder\.appName("Delta-Lake integration demo - create tables")\.enableHiveSupport()\.getOrCreate()## Create a DataFrame
data =  spark.createDataFrame([("100", "2015-01-01", "2015-01-01T13:51:39.340396Z"),
("101",  "2015-01-01", "2015-01-01T12:14:58.597216Z"),
("102", "2015-01-01", "2015-01-01T13:51:40.417052Z"),
("103",  "2015-01-01",  "2015-01-01T13:51:40.519832Z")],
["id", "creation_date",  "last_update_time"])spark.sql("""drop table if exists delta_table""")## Write a DataFrame as a Delta Lake dataset to the S3  location
spark.sql("""CREATE  TABLE IF NOT EXISTS delta_table (id string, creation_date string, 
last_update_time string)
USING delta location
's3://$APP_NAME/delta_table'""");data.writeTo("delta_table").append()
EOF
aws s3 cp $APP_LOCAL_HOME/delta_table.py $APP_S3_HOME/delta_table.py

4. 准备作业描述文件

cat << EOF > $APP_LOCAL_HOME/start-job-run.json
{"name":"$APP_NAME","applicationId":"$EMR_SERVERLESS_APP_ID","executionRoleArn":"$EMR_SERVERLESS_EXECUTION_ROLE_ARN","jobDriver":{"sparkSubmit":{"entryPoint":"s3://$APP_NAME/delta-test.py","sparkSubmitParameters":"--conf spark.hadoop.hive.metastore.client.factory.class=com.amazonaws.glue.catalog.metastore.AWSGlueDataCatalogHiveClientFactory --conf spark.sql.extensions=io.delta.sql.DeltaSparkSessionExtension --conf spark.sql.catalog.spark_catalog=org.apache.spark.sql.delta.catalog.DeltaCatalog --conf spark.jars=/usr/share/aws/delta/lib/delta-core.jar,/usr/share/aws/delta/lib/delta-storage.jar,/usr/share/aws/delta/lib/delta-storage-s3-dynamodb.jar"}},"configurationOverrides":{"monitoringConfiguration":{"s3MonitoringConfiguration":{"logUri":"$APP_S3_HOME/logs"}}}
}
EOF
jq . $APP_LOCAL_HOME/start-job-run.json

5. 提交 & 监控作业

export EMR_SERVERLESS_JOB_RUN_ID=$(aws emr-serverless start-job-run \--no-paginate --no-cli-pager --output text \--name apache-hudi-delta-streamer \--application-id $EMR_SERVERLESS_APP_ID \--execution-role-arn $EMR_SERVERLESS_EXECUTION_ROLE_ARN \--execution-timeout-minutes 0 \--cli-input-json file://$APP_LOCAL_HOME/start-job-run.json \--query jobRunId) && \
now=$(date +%s)sec && \
while true; dojobStatus=$(aws emr-serverless get-job-run \--no-paginate --no-cli-pager --output text \--application-id $EMR_SERVERLESS_APP_ID \--job-run-id $EMR_SERVERLESS_JOB_RUN_ID \--query jobRun.state)if [ "$jobStatus" = "PENDING" ] || [ "$jobStatus" = "SCHEDULED" ] || [ "$jobStatus" = "RUNNING" ]; thenfor i in {0..5}; doecho -ne "\E[33;5m>>> The job [ $EMR_SERVERLESS_JOB_RUN_ID ] state is [ $jobStatus ], duration [ $(date -u --date now-$now +%H:%M:%S) ] ....\r\E[0m"sleep 1doneelseecho -ne "The job [ $EMR_SERVERLESS_JOB_RUN_ID ] is [ $jobStatus ]\n\n"breakfi
done

6. 检查错误

JOB_LOG_HOME=$APP_LOCAL_HOME/log/$EMR_SERVERLESS_JOB_RUN_ID
rm -rf $JOB_LOG_HOME && mkdir -p $JOB_LOG_HOME
aws s3 cp --recursive $APP_S3_HOME/logs/applications/$EMR_SERVERLESS_APP_ID/jobs/$EMR_SERVERLESS_JOB_RUN_ID/ $JOB_LOG_HOME >& /dev/null
gzip -d -r -f $JOB_LOG_HOME >& /dev/null
grep --color=always -r -i -E 'error|failed|exception' $JOB_LOG_HOME
