[jira] [Created] (IOTDB-1506) CI fails because of JDBC connection exceptions

Steve Yurong Su created IOTDB-1506:
--------------------------------------

             Summary: CI fails because of JDBC connection exceptions 
                 Key: IOTDB-1506
                 URL: https://issues.apache.org/jira/browse/IOTDB-1506
             Project: Apache IoTDB
          Issue Type: Bug
            Reporter: Steve Yurong Su


The issue sometimes can be reproduced in 

IoTDBContinuousQueryIT & IoTDBTriggerExecutionIT.

 

A background data generator will be started when a ContinuousQueryIT or a TriggerExecutionIT runs. The data generator uses JDBC client to execute insertion statements. As we already know, the JDBC connection may break because of TException occurs and it does not have the retry logic.

 

To resolve the issue, we can catch the exception, create a new connection and execute the statement again.

 

A failed run example:
