> Team,
> When following the blog "Change Capture Using AWS Database Migration
> Service and Hudi" with my own data set, the initial load works perfectly.
> When issuing the command with the DMS CDC files on S3, I get the following
> error:
> {code}
> 20/03/24 17:56:28 ERROR HoodieDeltaStreamer: Got error running delta sync
> once. Shutting down
> org.apache.hudi.exception.HoodieException: Please provide a valid schema
> provider class! at
> org.apache.hudi.utilities.sources.InputBatch.getSchemaProvider(InputBatch.java:53)
>  at
> org.apache.hudi.utilities.deltastreamer.DeltaSync.readFromSource(DeltaSync.java:312)
> at
> org.apache.hudi.utilities.deltastreamer.DeltaSync.syncOnce(DeltaSync.java:226)
> {code}
> I tried using the  --schemaprovider-class
> org.apache.hudi.utilities.schema.FilebasedSchemaProvider.Source and provide
> the schema. The error does not occur but there are no write to Hudi.
> I am not performing any transformations (other than the DMS transform) and
> using default record key strategy.
> If the team has any pointers, please let me know.
> Thank you!

> Thank you Vinoth. I was able to find the issue. All my column names were in
> high caps case. I switched column names and table names to lower case and
> it works perfectly.
