# Validate that when a member joins a group, and it is missing data that was
# purged from group binary logs, the joiner member will proceed by cloning a
# a group member.
#
# Test:
# 0. The test requires two servers: M1 and M2.
# 1. Install clone plugin on server1.
# Commit some data and then purge all binary logs.
# Bootstrap a group on server1.
# 2. Install clone plugin on server2.
# Restart server with a monitoring process (mysqld_safe) if needed
# 3. Start GR, clone must be executed since recovery
# from binary logs is not possible.
# As a test variation, do not start on boot after cloning
# 4. Cleanup
