Hive query to quickly find table size (number of rows)

Question

Is there a Hive query to quickly find table size (i.e. number of rows) without launching a time-consuming MapReduce job? (Which is why I want to avoid COUNT(*).)

Answer 1

solution, though not quick
if the table is partitioned, we can count the number of partitions and count(number of rows) in each partition.
For example:, if partition by date (mm-dd-yyyy)

select partition_date, count(*) from  where  >= '05-14-2018' group by
