> Hi Guys,
>
> Environment: AWS EMR 6.4 / Hudi v0.8.0
> Problem: I have a MoR table wich is ingested by DeltaStremer (batch style:
> every 5 minutes from Kafka), and after a certain time, DeltaStremer stops
> working with a message like this:
>
> {{diagnostics: User class threw exception:
> org.apache.hudi.exception.HoodieRollbackException: Found commits after time
> :20220131215051, please rollback greater commits first}}
>
> It is usually a replace commit, I would say I am pretty sure in this.
> I have commits in the timeline:
>
> 20220131214354<-before
> 20220131215051<-error message
> 20220131215514<-after
>
> So as it was told to me, I try to rollback with the following steps in
> hudi-cli:
> 1.) connect --path s3://scgps-datalake/iot_raw/ingress_pkg_decoded_rep /
> SUCCESS
> 2.) savepoint create --commit 20220131214354 --sparkMaster local[2] / SUCCESS
> 3.) savepoint rollback --savepoint 20220131214354 --sparkMaster local[2] /
> FAILED
> 4.) savepoint create --commit 20220131215514 --sparkMaster local[2] / SUCCESS
> 5.) savepoint rollback --savepoint 20220131215514 --sparkMaster local[2] /
> FAILED
>
> Long story short, if I run a situation like this I am not able to solve it
> with the known methods ;) - My use-case is working progress, but I cannot go
> prod with an issue like this.
>
> My question, what would be the right steps / commands to solve an issue like
> this, and be able to restart deltastremer again.
>
> This table, does not have dimension data, so I am happy to share the whole
> table if someone curiuous (if that is needed or would be helpful, lets talk
> in a private mail / slack about the sharing). ~15GB ;) it was stoped after a
> few run, actually after the 1st clustering.
>
> I use this clustering config in the DeltaStremer:
> hoodie.clustering.inline=true
> hoodie.clustering.inline.enabled=true
> hoodie.clustering.inline.max.commits=36
> hoodie.clustering.plan.strategy.sort.columns=correlation_id
> hoodie.clustering.plan.strategy.daybased.lookback.partitions=7
> hoodie.clustering.plan.strategy.target.file.max.bytes=268435456
> hoodie.clustering.plan.strategy.small.file.limit=134217728
> hoodie.clustering.plan.strategy.max.bytes.per.group=671088640
>
> I hope there is someone who can help me to tackle with this, becase if I able
> to solve this manually, I would be confident to go prod.
> So thanks in advance,
