@Glive I couldn't test it right now, but could you try the following?
beeline -u "jdbc:hive2://server.com:10200/default;user=bob;password='is your uncle'"
Within single quotes try to escape white space with a back slash(\), if it does not work.
Else, let beeline prompt you for the password:
beeline -u "jdbc:hive2://server.com:10200/default" -n bob -p
When it prompts you, enter the password. This was introduced in HIVE-13589
