# This test verifies that if the missing transactions on a joining members are
# above threshold the server will use clone as its recovery strategy
#
# 0. The test requires two servers: M1 and M2.
# 1. Install the clone plugin on server 1
# 2. Bootstrap server1 and add some data
# 3. Restart server 2 with a monitoring process (mysqld_safe) if needed
# 4. Setup the server so group replication starts on boot
# Install the clone plugin
# 5. Verify clone must not override joiner data.
# 6. On a empty server2 start group replication
# Wait for it to restart and come back
# Check clone was completed
# 7. Cleanup
