Description

I am running this on Flink ver.1.11.3: 

 

    val bsEnv: StreamExecutionEnvironment = StreamExecutionEnvironment.getExecutionEnvironment
    val bsSettings: EnvironmentSettings   = EnvironmentSettings.newInstance().useBlinkPlanner().inStreamingMode().build()

    val bsTableEnv: StreamTableEnvironment = StreamTableEnvironment.create(bsEnv, bsSettings)

    val cat = new GenericInMemoryCatalog("custom_catalog", "customDB")
    bsTableEnv.registerCatalog("custom_catalog", cat)
    bsTableEnv.useCatalog("custom_catalog")
    bsTableEnv.useDatabase("customDB")

    val createInputTableDDL =
      """
        |
        |CREATE TABLE kafkaTable (
        | user_id BIGINT,
        | item_id BIGINT,

        |)

    val createOutputTableDDL =

    bsTableEnv.executeSql(createInputTableDDL)
    bsTableEnv.executeSql(createOutputTableDDL)

    val result = bsTableEnv.sqlQuery(
      "SELECT HOP_START(timestamp1, INTERVAL '10' SECOND, INTERVAL '2' MINUTE) as strt, sum(item_id) as sum_ijh FROM kafkaTable " +
        "GROUP BY HOP(timestamp1, INTERVAL '10' SECOND, INTERVAL '2' MINUTE)"
    )

    result.executeInsert("kafkaOutTable")

When setting log level to TRACE, the job fails with this exception:
