Description

test step1:

create a partitioned hudi table (mor / cow)

val base_data = spark.read.parquet("/tmp/tb_base")
val upsert_data = spark.read.parquet("/tmp/tb_upsert")

base_data.write.format("hudi").option(TABLE_TYPE_OPT_KEY, MOR_TABLE_TYPE_OPT_VAL).option(PRECOMBINE_FIELD_OPT_KEY, "col2").option(RECORDKEY_FIELD_OPT_KEY, "primary_key").option(PARTITIONPATH_FIELD_OPT_KEY, "col0").option(KEYGENERATOR_CLASS_OPT_KEY, "org.apache.hudi.keygen.SimpleKeyGenerator").option(OPERATION_OPT_KEY, "bulk_insert").option(HIVE_SYNC_ENABLED_OPT_KEY, "true").option(HIVE_PARTITION_FIELDS_OPT_KEY, "col0").option(HIVE_PARTITION_EXTRACTOR_CLASS_OPT_KEY, "org.apache.hudi.hive.MultiPartKeysValueExtractor").option(HIVE_DATABASE_OPT_KEY, "testdb").option(HIVE_TABLE_OPT_KEY, "tb_test_mor_par").option(HIVE_USE_JDBC_OPT_KEY, "false").option("hoodie.bulkinsert.shuffle.parallelism", 4).option("hoodie.insert.shuffle.parallelism", 4).option("hoodie.upsert.shuffle.parallelism", 4).option("hoodie.delete.shuffle.parallelism", 4).option("hoodie.datasource.write.hive_style_partitioning", "true").option(TABLE_NAME, "tb_test_mor_par").mode(Overwrite).save(s"/tmp/testdb/tb_test_mor_par")

upsert_data.write.format("hudi").option(TABLE_TYPE_OPT_KEY, MOR_TABLE_TYPE_OPT_VAL).option(PRECOMBINE_FIELD_OPT_KEY, "col2").option(RECORDKEY_FIELD_OPT_KEY, "primary_key").option(PARTITIONPATH_FIELD_OPT_KEY, "col0").option(KEYGENERATOR_CLASS_OPT_KEY, "org.apache.hudi.keygen.SimpleKeyGenerator").option(OPERATION_OPT_KEY, "upsert").option(HIVE_SYNC_ENABLED_OPT_KEY, "true").option(HIVE_PARTITION_FIELDS_OPT_KEY, "col0").option(HIVE_PARTITION_EXTRACTOR_CLASS_OPT_KEY, "org.apache.hudi.hive.MultiPartKeysValueExtractor").option(HIVE_DATABASE_OPT_KEY, "testdb").option(HIVE_TABLE_OPT_KEY, "tb_test_mor_par").option(HIVE_USE_JDBC_OPT_KEY, "false").option("hoodie.bulkinsert.shuffle.parallelism", 4).option("hoodie.insert.shuffle.parallelism", 4).option("hoodie.upsert.shuffle.parallelism", 4).option("hoodie.delete.shuffle.parallelism", 4).option("hoodie.datasource.write.hive_style_partitioning", "true").option(TABLE_NAME, "tb_test_mor_par").mode(Append).save(s"/tmp/testdb/tb_test_mor_par")
