The problem caused by incorrect upgrade procedure.
In place upgrade to mysql 5.6 or 5.7 require shutdown with innodb_fast_shutdown=0 before upgrading packages.
For current state: install 5.5 binaries, start mysqld with skip-slave-start, prevent external connections from application, execute innodb_fast_shutdown=0, shutdown mysqld.
