-------------------------------

             Summary: The Jdbc-connector's  'lookup.max-retries' option implementation is different from the meaning
                 Key: FLINK-19684
                 URL: https://issues.apache.org/jira/browse/FLINK-19684
             Project: Flink
          Issue Type: Bug
          Components: Connectors / JDBC
            Reporter: CaoZhen


 

The code of 'lookup.max-retries' option :
{code:java}
for (int retry = 1; retry <= maxRetryTimes; retry++) {
      statement.clearParameters();
      .....
}  
{code}
From the code, If this option is set to 0, the JDBC query will not be executed.

 

From documents,  the max retry times if lookup database failed. [1]

When set to 0, there is a query, but no retry.

 

So,the code of 'lookup.max-retries' option should be:
{code:java}
for (int retry = 0; retry <= maxRetryTimes; retry++) {
      statement.clearParameters();
      .....
}  
{code}
