wuwenchi created HUDI-4558:
------------------------------

             Summary: lost 'hoodie.table.keygenerator.class' in 
hoodie.properties
                 Key: HUDI-4558
                 URL: https://issues.apache.org/jira/browse/HUDI-4558
             Project: Apache Hudi
          Issue Type: Bug
          Components: flink, flink-sql
            Reporter: wuwenchi


I created a hudi table through flinksql and specified 
hoodie.datasource.write.keygenerator.type as complex, because in document, 
hoodie.datasource.write.keygenerator.type is "Easily configure one the built-in 
key generators, instead of specifying the key generator class". 

But in hoodie.properties, I did not see the property 
hoodie.table.keygenerator.class which is required in document.


{code:sql}
create table tb1(
  pk1 string,
  par2 string,
  PRIMARY KEY(pk1) NOT ENFORCED
)
PARTITIONED BY (`par2`)
with (
  'connector' = 'hudi',
  'path' = '.....',
  'connector' = 'hudi',
  'hoodie.datasource.write.keygenerator.type' = 'COMPLEX',
  'table.type' = 'MERGE_ON_READ',
  'write.operation' = 'upsert'
)
{code}
{panel:title=}
hoodie.table.keygenerator.class
Key Generator class property for the hoodie table
Default Value: N/A ({*}{color:#FF0000}Required{color}{*})
Config Param: KEY_GENERATOR_CLASS_NAME
{panel}
