# Test case to verify that main thread which start group_replication waits
# for applier thread to properly initialized before calling its termination
# in case of failure.
#
# Test:
# 0. The test requires two servers M1 & M2.
# 1. START GROUP_REPLICATION on server1.
# Also set group_replication_applier_thread_init_wait
# dbug_sync point to make applier thread wait.
# 2. KILL START GROUP_REPLICATION query and connection,
# to simulate CTRL-C/Z'ED `START GROUP_REPLICATION`.
# 3. Reap the killed command and reset debug point.
# 4. Restart Group Replication on server1
# 5. Clean up.
