你好， 现在yarn-session上还是可以提交新作业的。只是运行时无法分配slot，报错无法解析 resourcemanager 地址。
如果是RM leadership丢失的话， 1. 怎么可以确认是leader丢失呢？ 2. 通常是什么原因造成的呢？比如网络延迟？或者机器负载过高？ 3. 有什么办法可以恢复吗？ Xintong Song <[email protected]> 于2020年8月25日周二 下午5:26写道： > > > > 出现这个报错后就提交不了任务了 > > > 我确认一下，你之前这句话的意思，是出现这个报错之后，新的作业不能提交了，还是新的作业能提交但是提交之后页报这个找不到 RM 的错？ > > 从 RM 心跳超时但是整个进程还在运行这个现象来看，比较符合 RM leadership 丢失的情况，这种情况下 RM 会停止服务。 > 如果是新的作业干脆就无法提交了，也符合 rest server leadership 丢失的情况。 > > 我目前怀疑是 HA 出现问题，导致 RM 和 rest server 都认为自己不再是 leader，但是又迟迟没有新的 leader 产生。所以对于 > JobMaster，由于没有发现有新的 RM leader，就会一直尝试重连原来的 RM，而对于 rest server 的表现则是找不到新的 > leader 无法提交新的作业。 > > Thank you~ > > Xintong Song > > > > On Tue, Aug 25, 2020 at 4:50 PM song wang <[email protected]> > wrote: > > > hi, Xintong： > > > > 我仔细查看了下日志，发现在报错"Could not resolve ResourceManager address"之前有如下日志： > > > > 2020-08-22 05:39:24,473 INFO > org.apache.flink.runtime.jobmaster.JobMaster > > -
