Hi, I'm trying a simple flink job that reads data from a kafka topic and creates a Hive table.
I'm following the steps from here <https://ci.apache.org/projects/flink/flink-docs-release-1.13/docs/connectors/table/hive/overview/#connecting-to-hive> . Here's my code: import org.apache.flink.table.api.EnvironmentSettings; import org.apache.flink.table.api.Table; import org.apache.flink.table.api.TableEnvironment; import org.apache.flink.table.catalog.hive.HiveCatalog; EnvironmentSettings settings = EnvironmentSettings.newInstance().useBlinkPlanner().inStreamingMode().build(); TableEnvironment tableEnv = TableEnvironment.create(settings); String name = "myhive"; String defaultDatabase = "harsh_test"; String hiveConfDir = "/etc/hive/conf"; HiveCatalog hive = new HiveCatalog(name, defaultDatabase, hiveConfDir); tableEnv.registerCatalog(name, hive); // set the HiveCatalog as the current catalog of the session tableEnv.useCatalog(name); tableEnv.executeSql("CREATE TABLE IF NOT EXISTS transactions (\n" + " `created_at` TIMESTAMP(3) METADATA FROM 'timestamp',\n" + " `partition` BIGINT METADATA VIRTUAL,\n" + " `offset` BIGINT METADATA VIRTUAL,\n" + " account_id BIGINT,\n" + " amount BIGINT,\n" + " transaction_time TIMESTAMP(3),\n" + " WATERMARK FOR transaction_time AS transaction_time - INTERVAL '5' SECOND\n" + ") WITH (\n" + " 'connector' = 'kafka',\n" + " 'topic' = 'flink-stream-table',\n" + " 'properties.bootstrap.servers' = '<BROKER_ADDRESS>:9092',\n" + " 'scan.startup.mode' = 'earliest-offset',\n" + " 'format' = 'csv'\n" + ")"); Table table = tableEnv.sqlQuery("Select * from transactions"); table.execute().print(); The code builds successfully, but I'm getting the following runtime error: Caused by: java.util.concurrent.CompletionException: java.lang.NoClassDefFoundError: org/apache/kafka/common/serialization/ByteArrayDeserializer at java.util.concurrent.CompletableFuture.encodeThrowable(CompletableFuture.java:273) at java.util.concurrent.CompletableFuture.completeThrowable(CompletableFuture.java:280) at java.util.concurrent.CompletableFuture$AsyncSupply.run(CompletableFuture.java:1606) ..
