[jira] [Comment Edited] (AIRAVATA-2376) Duplicating experiment records in Experiment statistics and Experiment browse

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

I've got this working now by using the MariaDB jar.  Since [version 1.1.8|https://mariadb.com/kb/en/mariadb/mariadb-java-client-118-changelog/] the MariaDB JDBC driver defaults to using fractional seconds.  So the solution required two changes:
* update the column as in the previous comment
* switch to using the MariaDB JDBC jar

Still to do:
* (/) update Ansible scripts to create a airavata-server.properties with mariadb JDBC driver
* (/) also update Ansible scripts to download the MariaDB JDBC driver and remove the MySQL JDBC driver
----

This is done now and I've merged my branch to develop but I want to test it as part of the dev migration to Jetstream before being putting this into production.

> When experiments are launched there are two records in EXPERIMENT SUMMARY table for LAUNCHED and EXECUTING state which has the exact same state change time. In PGA however two records show up for the same experiment and with same status. e.g.: two exact records for a single experiment. This only appears until the experiment is FAILED or COMPLETED. But both users and gateway admins notices this and this needs fixing.
