upgrade to 0.54 problem about mysql-master-ha HOT 5 CLOSED

Did you upgrade mha4mysql-node deb package to 0.54 as well as mha4mysql-manager?

yes

dpkg -l | grep mha

ii  mha4mysql-manager                   0.54-0                       Master 
High Availability Manager and Tools for MySQL, Manager Package
ii  mha4mysql-node                      0.54-0                       Master 
High Availability Manager and Tools for MySQL, Node Package

This is strange. Your error message happens if MHA Node package or NodeUtil.pm 
is not updated to 0.54 so I think MHA Manager refers older NodeUtil.pm. Would 
you please do below and let me know?

- Check all NodeUtil.pm file on your server (i.e. updatedb; locate NodeUtil.pm)
- Get md5sum. In 0.54 NodeUtil.pm md5 checksum should be as below.
$ md5sum /usr/share/perl5/MHA/NodeUtil.pm
65a0094af5176d9dcd8a44028ec14bb1
- Open NodeUtil.pm and check there is a "escape_for_shell" function

Yeah!! you fixed my problem 

i have another install  in /usr/local/share/perl/5.10.1/MHA. 
after remove it, it's ok with 0.54 version.

thanks a lot
