Failed jenkins run with PS 5.7; seems to be failed version check

From installdb.log:

2017-01-09 07:08:57 [WARNING] mysql_install_db is deprecated. Please consider switching to mysqld --initialize
2017-01-09 07:08:57 [ERROR]   The data directory needs to be specified.

From mysql.log:

2017-01-09T07:09:08.958202Z 0 [Warning] Failed to open optimizer cost constant tables

2017-01-09T07:09:08.958396Z 0 [ERROR] Fatal error: Can't open and lock privilege tables: Table 'mysql.user' doesn't exist

was this due to the swapback to MID for MD? or is mysqld --initialize-insecure still being used?

Seems to be related to -> #54
From console log:

07:08:53 ./include/ptb_core.inc: line 412: /bin/mysqld: No such file or directory
07:08:53 ./include/ptb_core.inc: line 413: /bin/mysqld: No such file or directory

So version check failed there.
