Getting last day of previous month in HIVE query

Question

I am new to HIVE and I need to get the last day of previous month from a table in hive.

SQL equivalent ---

select last_day(add_months(sysdate,-1)) from dual;

I could only get previous day in the internet which is something like

select * 
from table1 
where dt >= from_unixtime(unix_timestamp()-1*60*60*24, 'yyyyMMdd');

could someone please help me with the query?

Thanks Rakesh
