# GTID_PURGED can't be set while GR plugin is running. This test shall verify
# that.
#
# Test:
# 0) The test requires two servers: M1 and M2.
# 1) Execute a few transactions locally on M1 before starting GR.
# 2) Set GTID_PURGED a few transactions ahead on M1.
# 3) Start GR on both members and verify that the group stabilizes itself.
# 4) Try to modify the GTID_PURGED  with GR running. It should fail with
#    ER_UPDATE_GTID_PURGED_WITH_GR on each member.
# 5) Stop GR and verify that it is possible to set GTID_PURGED again on both
#    members.
# 6) Cleanup.
