nebula2.0.1用spark-connect reader读取点然后写入hive，读取止20%左右报错
您好，这个192.168.1.220 是本地ip还是服务器ip呀？或者是什么？
贴一下更多日志吧，你是直接跑example吗，你要先确保你的NebulaGraph中有tmp这个space，并且有test这个tag
这个是NebulaGraph meta服务所在的机器ip
space与tag都是有的，代码读取少量进行点进行展示是没问题的，点总量有7千万左右，读出1千3百万左右就会报错 spark版本 2.4.8 nebula 2.0.1
这个是报错日志

你用netstat -a查看下是否有TIME_WAIT的连接，如果是的话 可以修改下系统支持的tcp连接数。
https://customer.precisely.com/s/article/Error-java-net-BindException-Address-already-in-use-connect-in-EngageOne-Vault?language=en_US
查了一下没有TIME_WAIT的连接
established 连接数有多少，space有多少个partition？看看是正常的连接去读取数据 还是存在泄漏
您好，这个读取错误怎么解决呀，我也遇到了，也发了帖子，暂时没有人回复呢
如果堆栈一样，那你贴一下下下面的的信息
问题解决了，服务端的tcp连接数量没有问题，我是用idea在本地跑的代码，把本机的tcp连接数量调高 65535，把tcp连接保留时间调短 30s，然后就可以正常读取了
如果报错一致的话可以试着调大一下本机的最大tcp连接数量
