MySQL Replication Health is NOT OK!

======================================

mha version :  node-0.54 manager-0.55
mysql version : 5.6.15-rel63.0-log
OS version : centos 6.4 x_85 64

1,some parameters in my.cnf on both master and slave

 relay_log_info_repository=TABLE
 master_info_repository=TABLE

2, MHA app1.cnf 

[server default]
manager_log=/var/log/managemha.log
manager_workdir=/var/log/managemha
master_ip_failover_script="/usr/local/bin/master_ip_failover"
master_ip_online_change_script="/usr/local/bin/master_ip_online_change"
password=xxxooo
ping_interval=4
ssh_connection_timeout=15
ping_type=CONNECT
remote_workdir=/data/nodemha
repl_password=xxxx
repl_user=repl
ssh_port=22
ssh_user=root
user=root

[server1]
candidate_master=1
ignore_fail=1
hostname=192.168.100.55
master_binlog_dir=/data/percona-data-3307
port=3307

[server2]
candidate_master=1
ignore_fail=1
hostname=192.168.100.55
master_binlog_dir=/data/percona-data-3306
port=3306

192.168.100.55:3306 is the master while 192.168.100.55:3307 is the slave. 

look this(192.168.100.55:3307):

(user:root  time: 11:44 port: 3307)[db: (none)]select * from 
mysql.slave_relay_log_info;

Would you please show the result of the following command on the master 
(192.168.100.55:3306)?

SHOW SLAVE STATUS

The error code path is entered when parsing slave servers only. So I assume on 
3306 slave definition exists. If it exists, would you please remove slave 
definition by RESET SLAVE ALL and try again?

after testing ,i found that if set  relay_log_info_repository=TABLE and 
master_info_repository=TABLE   MHA also check table mysql.slave_relay_log_info 
on master ,so when mha found there is nothing in mysql.slave_relay_log_info 
then produces errors . 

solution:
modify my.cnf on the master (192.168.100.55:3306)
 # relay_log_info_repository=TABLE 
 # master_info_repository=TABLE
then restart master

everything is ok 

thank you ！

I met this issue recently, maybe a master should not specialize the two slave 
parameters, so remove them in my.cnf is correct solution,  mha-0.56 still has 
the issue.
