[SUPPORT] AWSDmsAvroPayload not found querying _rt table MoR

[Xiaohan-Shen]

Describe the problem you faced

When I tried to query _rt table using select count(*) from table_rt through Hive or Spark SQL, an exception is thrown saying AWSDmsAvroPayload not found. If I query _ro table or CoW table, it's working well.

To Reproduce

Steps to reproduce the behavior:

1. Start EMR 6.5.0, run DeltaStreamer to load a Hudi MoR table from DMS with these configs:

spark-submit 
--jars /usr/lib/spark/external/lib/spark-avro.jar,/usr/lib/hudi/hudi-spark-bundle.jar,/usr/lib/hudi/hudi-utilities-bundle.jar 
--class org.apache.hudi.utilities.deltastreamer.HoodieDeltaStreamer 
--packages org.apache.hudi:hudi-spark-bundle_2.12:0.9.0,org.apache.spark:spark-avro_2.12:3.0.1 
--master yarn --deploy-mode client /usr/lib/hudi/hudi-utilities-bundle.jar 
--table-type MERGE_ON_READ 
--source-ordering-field timestamp 
--source-class org.apache.hudi.utilities.sources.ParquetDFSSource 
--target-base-path s3://mysql-data-replication/HATtrick-sf10/MERGE_ON_READ_hudi_HAT/FRESHNESS1 
--target-table FRESHNESS1 
--transformer-class org.apache.hudi.utilities.transform.AWSDmsTransformer 
--continuous 
--hoodie-conf hoodie.datasource.write.recordkey.field=F_CLIENTNUM 
--hoodie-conf hoodie.datasource.write.partitionpath.field="" 
--hoodie-conf hoodie.deltastreamer.source.dfs.root=s3://mysql-data-replication/HATtrick-sf10/HAT/FRESHNESS1 
--payload-class org.apache.hudi.payload.AWSDmsAvroPayload 
--hoodie-conf hoodie.datasource.write.keygenerator.class=org.apache.hudi.keygen.NonpartitionedKeyGenerator 
--hoodie-conf hoodie.datasource.hive_sync.table=FRESHNESS1 
--hoodie-conf hoodie.datasource.hive_sync.partition_extractor_class=org.apache.hudi.hive.NonPartitionedExtractor 
--hoodie-conf hoodie.datasource.hive_sync.use_jdbc=true 
--hoodie-conf hoodie.datasource.hive_sync.jdbcurl=jdbc:hive2://localhost:10000 
--hoodie-conf hoodie.datasource.hive_sync.enable=true 
--hoodie-conf hoodie.datasource.hive_sync.database=HAT 
--enable-hive-sync 

2. Query the _rt table when a change is captured by DeltaStreamer through Hive: select count(*) from database.table_rt;

Expected behavior

The query for _rt tables should run without error and provide more fresh results.

Environment Description

• Hudi version : 0.9.0

• Spark version : 3.1.2

• Hive version : 3.1.2

• Hadoop version : 3.2.1-amzn-5

• Storage (HDFS/S3/GCS..) : S3

• Running on Docker? (yes/no) : no

Additional context

I tried to include hudi-utilities-bundle.jar directly to hive.aux.jars.path, but no luck.

@Xiaohan-Shen If you are using Hudi jars from EMR like --jars /usr/lib/spark/external/lib/spark-avro.jar,/usr/lib/hudi/hudi-spark-bundle.jar,/usr/lib/hudi/hudi-utilities-bundle.jar, you don't need to put in OSS packages with --packages org.apache.hudi:hudi-spark-bundle_2.12:0.9.0,org.apache.spark:spark-avro_2.12:3.0.1 .

@rahil-c @umehrot2 could you folks help here regarding the EMR setup?

[Xiaohan-Shen]

@yihua Thanks for the reply! Not sure if this is relevant to the issue here, but I tried to run without —packages, and there was some sort of ClassNotFound exception when running DeltaStreamer. I am also confused of why, but if I run it with these —packages, there is no exception running deltastreamer.

[Xiaohan-Shen]

@yihua @rahil-c @umehrot2 Sorry to interrupt! Any suggestion on how I can work around this ClassNotFound issue?

[Xiaohan-Shen]

@yihua @umehrot2 Any updates on this issue? Let me know if there is other information I need to provide for debugging!

[nsivabalan]

here is my inference so far.

to run deltastreamer, you just need hudi-utilities-bundle. spark-bundle in addition is not required.

--jars /usr/lib/spark/external/lib/spark-avro.jar,/usr/lib/hudi/hudi-spark-bundle.jar,/usr/lib/hudi/hudi-utilities-bundle.jar 
--packages org.apache.hudi:hudi-spark-bundle_2.12:0.9.0,org.apache.spark:spark-avro_2.12:3.0.1 

From your command, looks like you are adding spark bundle via --packages and both spark and utilties. can you remove pulling in spark bundles. and wrt utilities, try to pull in just once. also, you don't even need to pull in via --packages. bcoz, spark-submit expects an app jar anyways.

spark-submit
.
.
--class CLASSNAME
JAR_LOCATION
param1
param2

[nsivabalan]

and w/ hudi 0.12, you don't need spark-avro at all. so you can ignore that as well.

[rahil-c]

The /usr/lib/hudi/hudi-utilities-bundle.jar is needed, And the spark-avro jar is required if your running any hudi release under 0.11.0 (if you are on 0.11.0 or above you can omit this jar). Finally you can get rid of spark-bundle since delta streamer is from utilities.

Here is a basic example

spark-submit --class org.apache.hudi.utilities.deltastreamer.HoodieDeltaStreamer \
            --jars /usr/lib/spark/external/lib/spark-avro.jar \
            --master yarn \
            --deploy-mode client \
            /usr/lib/hudi/hudi-utilities-bundle.jar \
            ...
            ... rest of params
            ...

going ahead and closing this one. feel free to reopen or create a new one. would be happy to help.
