Set the number of mapper in hive
Hi everyone,

My cluster also runs HBase for real time processing. Hive query (on a big
table) occupies all the map tasks so that the other service cannot run
properly.
Does anyone know how to limit the number of running map in hive?
I see mapred.reduce.tasks in the configuration properties, but I don't see
the configuration for mapper.

Thank you.

Regards,
Philips
