Hi
场景:1 tm 三个slot,run了三个job
三个job 运行的时候 出现了 ck 过程中空指针异常,导致任务一致重启。最终导致`Metaspace` 空间占满,出现
`java.lang.OutOfMemoryError: Metaspace. 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~~~
