   @logan-jun hudi table name will be used to generate avro schema record name 
and hyphen is not a valid character in avro schema name. see 
https://avro.apache.org/docs/1.8.2/spec.html#names
   
   > The name portion of a fullname, record field names, and enum symbols must:
   > start with [A-Za-z_]
   > subsequently contain only [A-Za-z0-9_]
   
   make the table name start with a letter and change hyphen to underscore 
should resolve the problem.
