msck repair table internally

[Souvikk Roy <so...@gmail.com>]

Hi all,

May be it is a common knowledge. Can anyone tell whether "msck repair
table" also spawns multiple mappers like entity (or multiple processes) to
perform.

We have a large external table to migrate from one hive to another, hence
we need to create it in the new hive and then repair it.

Before that, I need to know, internally how much resource it will use.
"Explain" on msck does not provide much details.

thanks
Souvik
