Hello, Celeborn community,

I would like to cancel the vote for Apache Celeborn 0.7.0-rc1 and
start a new vote for Apache Celeborn 0.7.0-rc2.

During the rc1 vote period, two issues were identified and fixed:

- CELEBORN-2399 (PR #3777): HA worker heartbeat using stateStartTime
  instead of actual time, causing healthy workers to be falsely marked
  lost. Fixed by restoring getTime().

- CELEBORN-2401 (PR #3779): Flipped the default of
  celeborn.client.spark.fetch.cleanFailedShuffle from false to true,
  based on the dev@ discussion. This reclaims stale shuffle data from
  FetchFailed retried stages and prevents disk pressure on shared clusters.

Both fixes have been merged into branch-0.7 and are included in rc2.

This is a call for a vote to release Apache Celeborn
0.7.0-rc2
