Apache flink 这意味着什么'；类型序列化程序工厂无法从配置'；加载其参数；？

运行此命令时出现问题

 ./bin/flink run -p 4 -q examples/gelly/flink-gelly-examples_*.jar --algorithm PageRank --input CSV --type integer --simplify directed --input_filename WikiTalk.txt --input_field_delimiter $'\t'     --output print

我使用的是虚拟机，我的集群由3个taskmanager组成，主任务是jobmanager和taskmanager（4个taskmanager和一个jobmanager）

部分例外

您使用的是哪种Flink版本？请直接指定gelly jar而不是使用blob重试好吗

examples/gelly/flink-gelly-examples_2.11_1.10.jar

我使用的是flink-1.7.2版本，是的，我尝试了，发现了相同的错误
