# This test verifies that the CHANGE MASTER command will only accept
# MASTER_USER and MASTER_PASSWORD as valid values for the recovery channel.
# All other options for the CHANGE MASTER will cause an error.
#
# Test:
# 0. The test requires two servers: M1 and M2.
# 1. Create a user on M1 to be used by the recovery channel. Bootstrap and start
# group on M1.
# 2. Add some data for recovery.
# 3. On M2, CHANGE MASTER with options apart from the MASTER_USER and
# MASTER_PASSWORD will cause error.
# 4. MASTER_PASSWORD for the CHANGE MASTER command will not be logged in the
# error log.
# 5. The password value is not logged in the error log.
# 6. CHANGE MASTER with valid options will work fine.
# 7. Ensuring the the two members are online.
# 8. Clean up.
