运行Apache Hudi deltastreamer时出错

Question

我正在尝试在AWS EMR上运行Hudi deltastreamer。按照此博客中的步骤操作。https://cwiki.apache.org/confluence/pages/viewrecentblogposts.action?key=HUDI

但是当我运行下面的spark提交时，错误出现了：

 Exception in thread "main" org.apache.hudi.com.beust.jcommander.ParameterException: Was passed main parameter '--table-type' but no main parameter was defined in your arg class
            at org.apache.hudi.com.beust.jcommander.JCommander.initMainParameterValue(JCommander.java:936)
            at org.apache.hudi.com.beust.jcommander.JCommander.parseValues(JCommander.java:752)
            at org.apache.hudi.com.beust.jcommander.JCommander.parse(JCommander.java:340)
            at org.apache.hudi.com.beust.jcommander.JCommander.parse(JCommander.java:319)

我运行的命令如下：

spark-submit --class org.apache.hudi.utilities.deltastreamer.HoodieDeltaStreamer \
--packages org.apache.spark:spark-avro_2.11:2.4.4 \
 --master yarn --deploy-mode client /usr/lib/hudi/hudi-utilities-bundle.jar \
--table-type COPY_ON_WRITE --source-ordering-field payment_date --source-class org.apache.hudi.utilities.sources.ParquetDFSSource \
--target-base-path s3://sakila-db/hudi-payment \
--target-table hudi-payment \
--transformer-class org.apache.hudi.utilities.transform.AWSDmsTransformer \
--payload-class org.apache.hudi.payload.AWSDmsAvroPayload \
--hoodie-conf hoodie.datasource.write.recordkey.field=order_id,hoodie.datasource.write.partitionpath.field=staff_id,hoodie.deltastreamer.source.dfs.root=s3://sakila-db/sakila/payment

请帮帮忙。

基于EMR releases，目前支持的hudi版本是0.5.0--孵化中。您正在遵循的步骤是针对0.5.1的，其中--table-type参数是0.5.0中旧--storage-type的新名称。

如果您使用的是0.5.0，请尝试使用--storage-type而不是--table-type重新运行
