EMR上运行Hudi DeltaStreamer成功但未同步至AWS Glue数据目录

操作背景 #

在EMR集群上运行Hudi DeltaStreamer，已确认S3目标路径s3a://my-bucket/data/my_database/my_target_table/下生成了.hoodie目录及预期的Parquet数据文件。

执行的spark-submit命令 #

spark-submit \
  --conf spark.hadoop.hive.metastore.client.factory.class=com.amazonaws.glue.catalog.metastore.AWSGlueDataCatalogHiveClientFactory \
  --deploy-mode cluster \
  --jars /usr/lib/spark/external/lib/spark-avro.jar,/usr/lib/hudi/hudi-spark-bundle.jar,/usr/lib/hudi/hudi-utilities-bundle.jar,/usr/lib/hudi/cli/lib/aws-java-sdk-glue-1.12.397.jar,/usr/lib/hive/auxlib/aws-glue-datacatalog-hive3-client.jar,/usr/lib/hadoop/hadoop-aws.jar,/usr/lib/hadoop/hadoop-aws-3.3.3-amzn-2.jar \
  --conf spark.sql.catalogImplementation=hive \
  --conf spark.sql.catalog.spark_catalog=org.apache.spark.sql.hudi.catalog.HoodieCatalog \
  --conf spark.sql.extensions=org.apache.spark.sql.hudi.HoodieSparkSessionExtension \
  --class org.apache.hudi.utilities.deltastreamer.HoodieDeltaStreamer /usr/lib/hudi/hudi-utilities-slim-bundle.jar \
  --table-type COPY_ON_WRITE \
  --source-class org.apache.hudi.utilities.sources.AvroDFSSource \
  --source-ordering-field id \
  --target-base-path s3a://my-bucket/data/my_database/my_target_table/ \
  --sync-tool-classes org.apache.hudi.aws.sync.AwsGlueCatalogSyncTool \
  --props file:///etc/hudi/conf/hudi-defaults.conf \
  --target-table my_target_table \
  --schemaprovider-class org.apache.hudi.utilities.schema.SchemaRegistryProvider \
  --enable-sync \
  --enable-hive-sync

Hive侧验证结果 #

通过beeline连接Hive可以正常查看对应数据库和表：

beeline -u jdbc:hive2://ip-1-1-1-1:10000
Connecting to jdbc:hive2://ip-1-1-1-1:10000

show databases;
+-----------------------------------+
|           database_name           |
+-----------------------------------+
| my_database                       |
+-----------------------------------+

show tables;
+----------------------------------------------------+
|                      tab_name                      |
+----------------------------------------------------+
| my_target_table                                    |
+----------------------------------------------------+

问题与排查情况 #

• 已按照Hudi官方文档指定--sync-tool-classes参数为org.apache.hudi.aws.sync.AwsGlueCatalogSyncTool，期望将Hudi表同步至AWS Glue数据目录
• DeltaStreamer任务执行成功且无报错，但Glue数据目录中未出现对应表
• 已修改/etc/spark/conf/log4j2.properties开启DEBUG日志：

log4j.rootCategory=DEBUG, console

• 查看DEBUG日志后仍未定位到同步失败的原因
