             Summary: Add log when create bulk format 
                 Key: FLINK-22617
                 URL: https://issues.apache.org/jira/browse/FLINK-22617
             Project: Flink
          Issue Type: Bug
          Components: Connectors / Hive
            Reporter: hehuiyuan


 Hive table sink  has some log that tells us whether to use native or mapred .

 

 
{code:java}
LOG.info("Hive streaming sink: Use MapReduce RecordWriter writer.");
LOG.info("Hive streaming sink: Use native parquet&orc writer.");
LOG.info(
 "Hive streaming sink: Use MapReduce RecordWriter writer because BulkWriter 
Factory not available.");
{code}
 

I have some ideas we can add log  to make it more  obvious when read hive for 
`createBulkFormatForSplit`.
