hi xuhaiLong,看日志发生的 checkpoint nullpointer 是个已知的问题,具体可以查看下面两个jira。 你用的jdk版本是多少呢?目前发现使用 jdk8_40/jdk8_60 + flink-1.10 会出现 checkpoint nullpointer,可以把jdk升级下版本试一下 https://issues.apache.org/jira/browse/FLINK-18196 https://issues.apache.org/jira/browse/FLINK-17479

The metaspace out-of-memory error has occurred. This can mean two things: either the job requires a larger size of JVM metaspace to load classes or there is a class loading leak. In the first case 'taskmanager.memory.jvm-metaspace.size' configuration option should be increased. If the error persists (usually in cluster after several job (re-)submissions) then there is probably a class loading leak which has to be investigated and fixed. The task executor has to be shutdown... ` 附件为部分异常信息 疑问: 1. 为什么会在 ck 时候出现空指针?(三个 job 为同一个 kafka topic,通过ck 恢复 job 可以正常运行,应该不是数据的问题) 2. 通过日志看,是可以重启的,为什么自动重启后还存在这个问题,导致一直重启? 感谢~~~ 从网易邮箱大师发来的云附件 08-07error.txt(730.4KB,2020年8月22日 11:37 到期) 下载
