Subject about hive limit optimization settings
Date Thu, 24 Jan 2013 23:12:34 GMT
Hi,

Do anyone know the meaning of these hive settings? The description of them are not clear to
me. If someone can give me an example of how they shall be used, it would be great!

<property>
  <name>hive.limit.row.max.size</name>
  <value>100000</value>
  <description>When trying a smaller subset of data for simple LIMIT, how much size
we need to guarantee
   each row to have at least.</description>
</property>

<property>
  <name>hive.limit.optimize.limit.file</name>
  <value>10</value>
  <description>When trying a smaller subset of data for simple LIMIT, maximum number
of files we can
   sample.</description>
</property>

Regards,

James
