nsivabalan opened a new pull request #4123:
URL: https://github.com/apache/hudi/pull/4123
## What is the purpose of the pull request
When rollbacks fail midway, and if writer comes up next time, a new rollback
is attempted for partially failed commits. This patch fixes this, so that the
same rollback instant is used and retried. This will ensure there are no
dangling inflight rollbacks in timeline.
## Brief change log
Fixed rollback impl in AbstractHoodieWriteClient to check for pending
rollbacks and re-use the same instead of creating a new rollback instant
everytime to do rollback of commits.
