How can I see the memory % that is used right now in Impala? Also I want to check the whole memory size

Best idea would be to use cloudera manager.
It shows health of impala. Queries running, which query taking more memory and kill them if needed.
Manage/distribute the memory between yarn, impala as well.
I am not sure about licensing and probably its not free but you can ask your CDH administrator.
Here is few screenshots from sample system -
