    Description

      refine_collection_shard_key_basic.js checks if entries associated with refineCollectionShardKey are correctly inserted into the changelog.
      In the case that the primary stepdown do to a failure, it is not guaranteed that these entries are committed on the changelog.
      In particular for every refineCollectionShardKey operation it could be possible to have:

      • one or more `refineCollectionShardKey.start` entry in the changelog SERVER-43201
      • one or zero `refineCollectionShardKey.end` entry in the changelog. SERVER-44099

      Unfortunately the two implemented solution failed to address the problem.
