Yes, you can do this. If you plan to run mysql_upgrade on each node
after upgrading, you may want to set wsrep_OSU_method to RSU before
doing so. I think this is especially important for this upgrade, since
mysql_upgrade in 10.0.19 calls REPAIR VIEW. That statement doesn't
exist in 10.0.15.

e.g.:

service mysql stop
yum update MariaDB-Galera-server MariaDB-client MariaDB-devel
MariaDB-shared galera-3
service mysql start
mysql --execute="SET GLOBAL wsrep_OSU_method=RSU;"
mysql_upgrade
mysql --execute="SET GLOBAL wsrep_OSU_method=TOI;"
