Chesnay Schepler commented on FLINK-25098: ------------------------------------------ >From the logs we can see that the JM tries to recover a job (which it derived >from the K8 config map), but is unable to find the jobgraph on disk in the HA >store. Can you expand a bit on when exactly this occurred? Was the job running fine, then ran into a JM failover, and then this issue occurred? How regularly does it occur? Does it run fine for a few days and then suddenly fail? > Jobmanager CrashLoopBackOff in HA configuration > ----------------------------------------------- > > Key: FLINK-25098 > URL: https://issues.apache.org/jira/browse/FLINK-25098 > Project: Flink > Issue Type: Bug > Components: Deployment / Kubernetes > Affects Versions: 1.13.2, 1.13.3 > Environment: Reproduced with: > * Persistent jobs storage provided by the rocks-cephfs storage class. > * OpenShift 4.9.5. > Reporter: Adrian Vasiliu > Priority: Critical > Attachments: jm-flink-ha-jobmanager-log.txt, > jm-flink-ha-tls-proxy-log.txt > > > In a Kubernetes deployment of Flink 1.13.2 (also reproduced with Flink > 1.13.3), turning to Flink HA by using 3 replicas of the jobmanager leads to > CrashLoopBackoff for all replicas. > Attaching the full logs of the {{jobmanager}} and {{tls-proxy}} containers of > jobmanager pod: > [^jm-flink-ha-jobmanager-log.txt] > [^jm-flink-ha-tls-proxy-log.txt] > Reproduced with: > * Persistent jobs storage provided by the {{rocks-cephfs}} storage class > (shared by all replicas - ReadWriteMany) and mount path set via > {{{}high-availability.storageDir: file///<dir>{}}}. > * OpenShift 4.9.5 and also 4.8.x - reproduced in several clusters, it's not > a "one-shot" trouble. > Remarks: > * This is a follow-up of > https://issues.apache.org/jira/browse/FLINK-22014?focusedCommentId=17450524&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-17450524. > > * Picked Critical severity as HA is critical for our product. -- This message was sent by Atlassian Jira (v8.20.1#820001)
