[jira] [Created] (HIVE-17614) Notification_sequence initialization using SQL statement which is compatible with 5.1 Version of Mysql

anishek created HIVE-17614:
------------------------------

             Summary: Notification_sequence initialization using SQL statement which is compatible with 5.1 Version of Mysql
                 Key: HIVE-17614
                 URL: https://issues.apache.org/jira/browse/HIVE-17614
             Project: Hive
          Issue Type: Improvement
          Components: HiveServer2
    Affects Versions: 3.0.0
            Reporter: anishek
             Fix For: 3.0.0


Since a lot of people are still using hive with 5.1 mysql as the rdbms for metastore, it will be helpful to have the initialization statement introduced as part of HIVE-16896 for mysql to be friendlier to these older versions. 

INSERT INTO `NOTIFICATION_SEQUENCE` (`NNI_ID`, `NEXT_EVENT_ID`) SELECT * from (select 1 as `NNI_ID`, 1 as `NOTIFICATION_SEQUENCE`) a  WHERE (select count(*) from `NOTIFICATION_SEQUENCE`) = 0;
