enable explicit_defaults_for_timestamp will impacts HDP3 metastore ???

[#1]

Hi ,

Am trying to install Airflow 1.10 , it requires explicit_defaults_for_timestamp to be enabled in mysql server 5.7. https://github.com/apache/incubator-airflow/blob/master/UPDATING.md#mysql-setting-required

we are using the same Mysql5.7 server as our HDP 3 metastore database.

If i enabled the property explicit_defaults_for_timestamp in mysql, will it impacts existing metastore.

we have checked with hortonworks support team , changing the explicit_defaults_for_timestamp in mysq will not impact hive metastore
