haospotai edited a comment on issue #1284: [SUPPORT] URL: https://github.com/apache/incubator-hudi/issues/1284#issuecomment-578983670 > @haospotai It looks like an issue with shading of jars -> The hadoop metastore jars are shaded in the bundle that you might be using but somehow a class hierarchy is expecting a non-shaded one ? > > How are you starting the python client ? Could you paste the libs you are passing ? Also, please raise a JIRA for further discussions ``` class FunHudi: def __init__(self, app_name): load_dotenv('../.env') # the lib passed # hudi-spark-bundle-0.5.0-incubating.jar spark_bundle = ROOT_DIR + "/resources/" + os.environ['HUDI_SPARK_BUNDLE'] self.host = os.environ['HDFS_HOST'] self.hive_base_path = os.environ['HIVE_BASH_PATH'] self.spark = SparkSession.builder \ .master(os.environ['SPARK_MASTER']) \ .appName(app_name) \ .config("spark.jars", spark_bundle) \ .config("spark.driver.extraClassPath", spark_bundle) \ .getOrCreate() def insert_data_hudi_sync_hive(self, tablename, data_hdfs): df = self.spark.read.json(data_hdfs) df.write.format("org.apache.hudi") \ .option("hoodie.datasource.write.precombine.field", "uuid") \ .option("hoodie.table.name", tablename) \ .option("hoodie.datasource.hive_sync.partition_fields", "partitionpath") \ .option("hoodie.datasource.write.partitionpath.field", "partitionpath") \ .option("hoodie.datasource.hive_sync.database", "default") \ .option("hoodie.datasource.hive_sync.enable", "true")\ .option("hoodie.datasource.hive_sync.table", tablename) \ .option("hoodie.datasource.hive_sync.jdbcurl", os.environ['HIVE_JDBC_URL']) \ .option("hoodie.datasource.hive_sync.username", os.environ['HIVE_USER']) \ .option("hoodie.datasource.hive_sync.password", os.environ['HIVE_PASSWORD']) \ .mode("Overwrite") \ .save(self.host + self.hive_base_path) ``` ``` class TestSoptaiHudi(unittest.TestCase): def setUp(self) -> None: load_dotenv('.env') self.host = os.getenv('HDFS_HOST') self.hudiclient = FunHudi("testApp") self.path = '/data/peoplejson.json' def test_insert_json_data_with_hudi(self): self.hudiclient.insert_json_data_with_hudi("people", self.path) def test_insert_data_hudi_sync_hive(self): self.hudiclient.insert_data_hudi_sync_hive("soptaitest", self.path) ``` The exception will be thrown by set ```"hoodie.datasource.hive_sync.enable", "true"``` Cuz the app syncs data to hive at the end
