# This test proves Group replication does not delete group_replication_applier
# channel on start of group replication post clone.
#
# Test:
# 0. The test requires two servers: M1 and M2.
# 1. Install clone plugin on server1.
# 2. Set PRIVILEGE_CHECKS_USER for GR applier channel and recovery channels.
# 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 and set threshold to 1.
# 5. Start GR and wait for server to reboot post clone.
# Joiner must fail to join the group.
# 6. Confirm value of PRIVILEGE_CHECKS_USER is preserved pre and post GR start.
# 7. Cleanup.
