这个错误是由于Flink在创建检查点存储时出现了问题。你可以尝试以下方法来解决这个问题：

1. 增加内存分配给Flink任务。你可以在启动Flink任务时，通过设置taskmanager.memory.process.size参数来增加内存分配。例如，将内存分配设置为2GB：

flink run -m yarn-cluster -yn 4 -yjm 2g -c com.example.MyJob /path/to/your/jarfile.jar

1. 检查你的Hudi配置是否正确。确保Hudi的配置文件（如hudi-conf.yaml）中的相关配置项设置正确，例如：

hoodie:
  datasource:
    write:
      type: hudi
      table: my_table
      hive_sync_enable: true
      hive_database: my_database
      hive_table: my_table
      hive_partition_fields: partition_field1,partition_field2
      hive_partition_extractor_class: org.apache.hudi.hive.MultiPartKeysValueExtractor
      hive_jdbc_url: jdbc:hive2://localhost:10000/my_database
      hive_username: hive_user
      hive_password: hive_password

1. 如果问题仍然存在，尝试升级Flink和Hudi到最新版本，或者查看Flink和Hudi的官方文档以获取更多关于这个问题的信息。
