Description

After serializing all commit metadata to Avro, bootstrap procedure tests are failing due to

Caused by: java.lang.NullPointerException: null of string of map of union of org.apache.hudi.avro.model.HoodieCommitMetadata

`HoodieCommitMetadata` map fields allow nullable. Need to investigate why serialization fails.
