# This test verifies the output of the show slave hosts.
#
# Test:
# 0. The test requires two servers: M1 and M2.
# 1. Bootstrap start a group on M2. Create table t1.
# 2. verify that the show slave hosts output is empty.
# 3. Stop the SQL_THREAD for channel group_replication_applier
#    so that M1 will be in recovering state when it is joined
#    to the group.
# 4. Start GR on M1. Wait until it is in RECOVERING state.
# 5. verify that show slave hosts on M2 shows M1.
# 6. start the SQL_THREAD for channel group_replication_applier
# 7. Wait until show slave hosts doesn't show server M2 in it's output.
# 8. Clean up.
