# Bug#13963 SHOW SLAVE HOSTS is unreliable
#
# Slaves only appear in the output of SHOW SLAVE HOSTS when report-host option
# is set. If an expected slave does not appear in the list, nobody knows
# whether the slave does not connect or has started without the "report-host"
# option.
#
# Remove the "Rpl_recovery_rank" column from SHOW SLAVE HOSTS, It is not
# implemented.
