Why does using pipe '|' terminate the second process, is there a way to prevent it?

Just to give some context, I'm trying to run this command echo "set hive.execution.engine=tez;" | hive hive terminates as soon as "set hive.execution.engine..." has been entered into the hive interactive shell, I want to it to stay in the hive interactive shell, but the shell then terminates and I'm back into the normal linux shell.
