What is the purpose of the change

This PR aims to fix FLINK-21569, where reading specific csv files will cause the job to hang forever. This is actually caused by a bug in Jackson (FasterXML/jackson-dataformats-text#191), so we're upgrading flink-shaded-jackson version in this fix.

Brief change log

  • Upgrade flink-shaded-jackson version to 2.12.1-13.0

Verifying this change

This change added tests and can be verified by running the added tests. It can also be tested by hand with the following steps.

  1. Download this csv file.
  2. Add the following test to a model which relies both on flink-csv and flink-table-planner-blink. For example the flink-sql-client module. Don't forget to change the file path in the DDL.
public class MyTest {

    @Test
    public void myTest() throws Exception {
        EnvironmentSettings settings = EnvironmentSettings.newInstance().inStreamingMode().build();
        TableEnvironment tEnv = TableEnvironmentImpl.create(settings);
        tEnv
                .getConfig()
                .getConfiguration()
                .setInteger(ExecutionConfigOptions.TABLE_EXEC_RESOURCE_DEFAULT_PARALLELISM, 2);
        tEnv
                .executeSql(
                        "CREATE TABLE `airports` (\n"
                                + "  `IATA_CODE` CHAR(3),\n"
                                + "  `AIRPORT` STRING,\n"
                                + "  `CITY` STRING,\n"
                                + "  `STATE` CHAR(2),\n"
                                + "  `COUNTRY` CHAR(3),\n"
                                + "  `LATITUDE` DOUBLE NULL,\n"
                                + "  `LONGITUDE` DOUBLE NULL,\n"
                                + "  PRIMARY KEY (`IATA_CODE`) NOT ENFORCED\n"
                                + ") WITH (\n"
                                + "  'connector' = 'filesystem',\n"
                                + "  'path' = 'file:///tmp/airports.csv',\n"
                                + "  'format' = 'csv',\n"
                                + "  'csv.allow-comments' = 'true',\n"
                                + "  'csv.ignore-parse-errors' = 'true',\n"
                                + "  'csv.null-literal' = ''\n"
                                + ")")
                .await();
        tEnv.executeSql("SELECT * FROM airports").print();
    }
}
