Fastest way to get the row count

[mahender bigdata]

Hi Team,

Is there any built-in command in hive to get ROWCOUNT of previous 
operation just like in SQL Server @@RowCount. For example: I have table 
with almost 2 GB of data per partition, We run select query on table 
with condition, which filters the records, we will be dumping those 
filtered records in to another table apart from inserting, we need 
insert ROWCOUNT inserted into another hive table. Rather than running 
Select count(1) or Explain commands, is there better way to get row 
count of affected row. (previous step row count)
