# Validate that when a server joins a group and is not able to find
# a suitable donor it errors out and does not block on join.
#
# Test:
# 0. The test requires three servers: M1, M2 and M3.
# 1. Create a group with three members and schedule a periodic event to create
#    some load in the group on M1.
# 2. Add suppressions.
# 3. Stop applier channel on M1 so that joinining members that will recover
#    from it will be blocked on recovery waiting for the View_change_log_event.
# 4. Stop and start M2 and M3. M2 and M3 will be in recovery.
# 5. Stop and start M1. M1 will be in recovery since all existent group members
#    are RECOVERING.
# 6. Clean up.
