# This test verifies that the CHANGE MASTER command is not logged in the binary
# log. Therefore it is not replicated as well.
#
# Test:
# 0. The test requires two servers: M1 and M2.
# 1. Create a user on M1 to be used by the recovery channel. Bootstrap
# GROUP on M1. Add some data for recovery.
# 2. Start GR on M2 post CHANGE MASTER with valid values. Grep for
# 'CHANGE MASTER' pattern in binary log data. Expect 0 count.
# 3. Grep for 'CHANGE MASTER' pattern in binary log of M1. Expect 0 count.
