Ethan Guo updated HUDI-3720:
----------------------------
Sprint: Hudi-Sprint-Mar-21
> Rollback reattempt fails if the commit to roll back is not present
> ------------------------------------------------------------------
>
> Key: HUDI-3720
> URL: https://issues.apache.org/jira/browse/HUDI-3720
> Project: Apache Hudi
> Issue Type: Bug
> Components: writer-core
> Reporter: Ethan Guo
> Assignee: Ethan Guo
> Priority: Blocker
> Labels: pull-request-available
> Fix For: 0.11.0
>
>
> Let's say C4 (RB_C1) is rolling back C1. If C4 fails just after the instant
> files of C1 are deleted and before C4 is transitioned from inflight to
> complete, next time when C4 rollback action is reattempted, the rollback
> cannot finish, due to the logic below, since the instant to rollback is not
> present.
>
> {code:java}
> BaseHoodieWriteClient
> public boolean rollback(final String commitInstantTime,
> Option<HoodiePendingRollbackInfo> pendingRollbackInfo, boolean skipLocking)
> throws HoodieRollbackException {
> ...
> if (commitInstantOpt.isPresent()) {
> ...
> } else {
> LOG.warn("Cannot find instant " + commitInstantTime + " in the timeline,
> for rollback");
> return false;
> } {code}
