Could you please paste the following command resultset on the slave 
192.168.100.55:3306?

select * from mysql.slave_relay_log_info;

oh ,thanks for your answers

192.168.100.55:3306 is the master while 192.168.100.55:3307 is the slave ,so 
there should be nothing in table slave_relay_log_info on 192.168.100.55:3306 . 

look this(192.168.100.55:3307):

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

I have the same problem.
I think it's maybe a bug in Server.pm in line 237:
master's mysql.slave_relay_log_info is empty, so get_relay_dir_file_from_table 
returns nothing.

  if ( $self->{relay_log_info_type} eq "TABLE" ) {
    my ( $relay_dir, $current_relay_log ) =
      MHA::SlaveUtil::get_relay_dir_file_from_table($dbh);
    $self->{relay_dir}         = $relay_dir;
    $self->{current_relay_log} = $current_relay_log;
    if ( !$relay_dir || !$current_relay_log ) {
      $log->error(
        sprintf(
" Getting relay log directory or current relay logfile from replication table 
failed on %s!",
          $self->get_hostinfo() )
      );
      croak;
    }
  }

Upgrading to 0.56 should resolve this issue.
