容器启动exitcode=2的异常，可能与flink sql配置单元连接器有关

flink（scala）exitcode=2在mvn清洁包之后

我有一个简单的flink任务，它从一个hive表的两列中读取数据 mysource ，将列相加，然后将结果写入另一个配置单元表 mysink ，其中 mysource 有2列 a bigint 以及 b bigint ，和 mysink 只有一列 c bigint .
作业提交成功，但我观察到它一直在重试。

我点击每一次尝试，他们只是显示这个。

然而，“日志”没有有用的信息-它抱怨日志库，但我相信它们实际上是警告，而不是错误。

这是用scala写的作业。

import org.apache.flink.streaming.api.scala.StreamExecutionEnvironment
import org.apache.flink.table.api.{EnvironmentSettings, SqlDialect}
import org.apache.flink.table.api.bridge.scala.StreamTableEnvironment
import org.apache.flink.table.catalog.hive.HiveCatalog

object HiveToyExample {
  def main(args: Array[String]): Unit = {
    val settings = EnvironmentSettings.newInstance.build
    val execEnv = StreamExecutionEnvironment.getExecutionEnvironment
    val tableEnv = StreamTableEnvironment.create(execEnv, settings)

    val hiveCatalog = new HiveCatalog(
      "myhive",
      "aiinfra",
      "/data/apache/hive/apache-hive-2.1.0-bin/conf/"
    )
    tableEnv.registerCatalog("myhive", hiveCatalog)
    tableEnv.useCatalog("myhive")

    tableEnv.getConfig.setSqlDialect(SqlDialect.DEFAULT)

    tableEnv
      .executeSql("""
          |INSERT INTO mysink
          |SELECT a + b
          |FROM mysource
          |""".stripMargin)
  }
}

这是pom.xml。

我就是这样 Package jar的。

mvn clean package

我就是这样做的。

flink run \
--yarnname scalaflink-hive-test \
-m yarn-cluster \
-yarnqueue datadev \
--class featurepipelines.ingestion.HiveToyExample \
./featurepipelines-0.1.1.jar

flink（scala）via intellij工作正常？！

因为我的本地环境能够访问上面提到的配置单元环境，所以我尝试运行 HiveToyExample 在intellij中，单击“运行”按钮。。。它工作得很好！

pyflink重写很好？！

因为逻辑很简单，所以我用pyflink重写了作业，看看会发生什么。这里显示了pyflink重写。

import os
from pyflink.datastream import StreamExecutionEnvironment
from pyflink.table import *
from pyflink.table.catalog import HiveCatalog

settings = EnvironmentSettings.new_instance().use_blink_planner().build()
exec_env = StreamExecutionEnvironment.get_execution_environment()
t_env = StreamTableEnvironment.create(exec_env, environment_settings=settings)

# There exists such a jar in the path

t_env.get_config().get_configuration().set_string(
    "pipeline.jars", f"file://{os.getcwd()}/deps/flink-sql-connector-hive-2.2.0_2.11-1.12.0.jar"
)

catalog_name = "myhive"
default_database = "aiinfra"
hive_conf_dir = "/data/apache/hive/apache-hive-2.1.0-bin/conf/"

hive_catalog = HiveCatalog(catalog_name, default_database, hive_conf_dir)
t_env.register_catalog(catalog_name, hive_catalog)
t_env.use_catalog(catalog_name)

TRANSFORM_DML = """
INSERT INTO mysink
SELECT a + b
FROM mysource
"""

t_env.get_config().set_sql_dialect(SqlDialect.DEFAULT)
t_env.execute_sql(TRANSFORM_DML).wait()

我就是这样做的。

flink run \
--yarnname pyflink-hive-test \
-m yarn-cluster \
-yD yarn.application.queue=tech_platform \
-pyarch pyflink1.12.0.zip \
-pyexec /data/software/pyflink1.12.0/bin/python \
-py /data/home/pal-flink/chenyisheng14418/feature-pipelines/pyflink/hive.py

令人惊讶的是，作业运行得很好—它很快就完成了，并将结果写入 mysink table。

为什么？

考虑到比较，我高度怀疑第一次运行失败是因为它打包不正确，即使我遵循flink文档，这可以通过查看我的pom来验证。
如果您正在构建自己的程序，那么mvn文件中需要以下依赖项。建议不要在结果jar文件中包含这些依赖项。您应该在运行时添加上述依赖项。

<!-- Flink Dependency -->
<dependency>
  <groupId>org.apache.flink</groupId>
  <artifactId>flink-connector-hive_2.11</artifactId>
  <version>1.12.0</version>
  <scope>provided</scope>
</dependency>

<dependency>
  <groupId>org.apache.flink</groupId>
  <artifactId>flink-table-api-java-bridge_2.11</artifactId>
  <version>1.12.0</version>
  <scope>provided</scope>
</dependency>

<!-- Hive Dependency -->
<dependency>
    <groupId>org.apache.hive</groupId>
    <artifactId>hive-exec</artifactId>
    <version>${hive.version}</version>
    <scope>provided</scope>
</dependency>

此外，我还将flink-sql-connector-hive-2.2.0\u 2.11-1.12.0.jar包含在我的flink发行版的/lib中，如flink docs中所建议的：
添加依赖项的推荐方法是使用绑定的jar。只有当捆绑的jar不能满足您的需要时，才应该使用单独的jar。
我错过了什么？

Hiveapache-flinkflink-sqlpyflink
