# ==== Purpose ====
#
# This test case will test the server behavior while enabling group replication
# on startup and changing the relay-log option.
#
# First, it will ensure that the server starts and enable GR if properly
# configured.
#
# Then, it will restart the server again change the relay-log option. The
# expected behavior is that GR should fail to start. It will remove the
# "group_replication_applier" channel manually in order to make it work
# properly on the next restart.
#
# Finally, the test will restart the server again and the GR plug-in should
# work fine.
