-------------------------------
Summary: 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
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}
