**_Tips before filing an issue_** - Have you gone through our [FAQs](https://hudi.apache.org/learn/faq/)? ✔️ - Join the mailing list to engage in conversations and get faster support at [email protected]. ✔️ - If you have triaged this as a bug, then file an [issue](https://issues.apache.org/jira/projects/HUDI/issues) directly. ✔️ **Describe the problem you faced** Using Hudi-Tool DeltaStreamer ingestion data from Kafka, and writing hudi-table successfully. But there was some error when I expected sync hive-tables and add patition in them. On top of that weirdness, hive-table can be created but the `patition adding process` called **NullPointerException** !! **To Reproduce** Steps to reproduce the behavior: 1. Using Debezium capture MySQL data into Kafka and enabling Kafka-Connector with Confluent Schema Registry managing the schema; 2. Prepare the Environment including `deploy Spark-Master/Worker`, `start Hive-MetaStore Server`. 3. Run the Spark Job via **spark-submit** script: ```bash spark-submit \ --jars "/home/hadoop/app/spark/ex_jar/hudi-utilities-bundle_2.12-0.12.0.jar,/home/hadoop/app/spark/ex_jar/spark-avro_2.12-3.2.2.jar" \ --master spark://web-65:7077 \ --deploy-mode cluster \ --driver-memory 1g \ --driver-cores 2 \ --executor-memory 1g \ --total-executor-cores 2 \ --class org.apache.hudi.utilities.deltastreamer.HoodieDeltaStreamer \ /home/hadoop/app/spark/ex_jar/hudi-utilities-bundle_2.12-0.12.0.jar \ --table-type COPY_ON_WRITE \ --op UPSERT \ --target-base-path cosn://bigdata-1252394470/hudi/cdc/mysql/table2 \ --target-table table2 \ --continuous \ --min-sync-interval-seconds 60 \ --source-class org.apache.hudi.utilities.sources.debezium.MysqlDebeziumSource \ --payload-class org.apache.hudi.common.model.debezium.MySqlDebeziumAvroPayload \ --source-ordering-field id \ --hoodie-conf schema.registry.url=http://web-65:8181 \ --hoodie-conf hoodie.deltastreamer.schemaprovider.registry.url=http://web-65:8181/subjects/debezium-cdc-server-mysql2.test_db.table2-value/versions/latest \ --hoodie-conf hoodie.deltastreamer.source.kafka.value.deserializer.class=io.confluent.kafka.serializers.KafkaAvroDeserializer \ --hoodie-conf hoodie.deltastreamer.source.kafka.topic=debezium-cdc-server-mysql2.test_db.table2 \ --hoodie-conf bootstrap.servers=web-65:9092 \ --hoodie-conf auto.offset.reset=earliest \ --hoodie-conf hoodie.datasource.write.recordkey.field=id \ --hoodie-conf hoodie.datasource.write.partitionpath.field=u_name \ --enable-sync \ --sync-tool-classes org.apache.hudi.hive.HiveSyncTool \ --hoodie-conf hoodie.datasource.hive_sync.partition_extractor_class=org.apache.hudi.hive.MultiPartKeysValueExtractor \ --hoodie-conf hoodie.datasource.write.hive_style_partitioning=true \ --hoodie-conf hoodie.datasource.hive_sync.enable=true \ --hoodie-conf hoodie.datasource.hive_sync.database=default \ --hoodie-conf hoodie.datasource.hive_sync.table=hudi_mysql_table2 \ --hoodie-conf hoodie.datasource.hive_sync.partition_fields=u_name \ --hoodie-conf hoodie.datasource.hive_sync.use_jdbc=false \ --hoodie-conf hoodie.datasource.hive_sync.metastore.uris=thrift://web-65:9083 \ --hoodie-conf hoodie.datasource.hive_sync.mode=hms ``` > my hostname is **web-65**, all component deployed on this machine except ZK\KAFKA. **Expected behavior** Hive table could be created and patition(s) be added. **Environment Description** * Hudi version : 0.12.0 * Spark version : 3.2.2 * Hive version : 2.3.9 * Hadoop version : 2.7.5 (Useless, only for starting hive-metastore process) * Storage (HDFS/S3/GCS..) : Tencent COS * Running on Docker?
