HandlerSocket is a NoSQL plugin for MySQL, working as a daemon inside the mysqld process, to accept tcp connections, and execute requests from clients. HandlerSocket does not support SQL queries; instead it supports simple CRUD operations on tables.
I upgraded from mysql 5.6.16 to 5.6.22 and the server now hangs on shutdown, requiring a kill -9. Commenting out the handlersocket lines in /etc/my.cnf reproducibly eliminates the issue.
