nsivabalan opened a new pull request #5002:
URL: https://github.com/apache/hudi/pull/5002
## What is the purpose of the pull request
when Deltastreamer consumes an empty batch, but checkpoint moved ahead, hudi
injects NullSchemaProvider as part of consumed InputBatch. Which returns null
schema (Schema.create(Schema.Type.NULL)) schema when asked for source or target
schema. So, this gets serialized into commit metadata and later runs into
issues when table schema is fetched.
Fix: when serializing the schema to commit metadata, we avoid adding the
entry if its null schema (Schema.create(Schema.Type.NULL)).
