nsivabalan opened a new pull request #4971:
URL: https://github.com/apache/hudi/pull/4971
## What is the purpose of the pull request
If clustering/compaction rollback failed mid-way, if rollback of a pending
clustering/compaction is re-attempted, a new rollback instant will be
generated. We would want to retry using the same rollback instant. Main
motivation is that, the old failed rollback instant is never cleaned up. And so
it could lead to liveness issues w/ metadata table.
## Brief change log
- Fixed rolling back of pending clustering/compaction to re-use rollback
instant if present.
