Hive query processor

Hi,

 

In Apache hive, I come across "Hive Query Processor". But I couldn't understand what exactly these 10 points meant for. Please explain precisely.

 

Here is the link..

Re: Hive query processor

Looks like the doc already contains explanation of each component and what they do, and they seem to be reasonable to me.

Not sure which part that you do not understand.

Hi EricL,

 

Thanks. I just want to clarify:- Whether these 10 components come into picture, only when we run a query in Hive ?
