Hi, Bejoy.
I find the mapred.min.split.size in mapred-default.xml, but there is
no mapred.max.split.size property.
I'm using hadoop 0.20.205.0.
Maybe only newer versions support mapred.max.split.size?

Hi, Majid.
I think you don't need know about pig, but it will help if you have
some SQL knowledge.

hi guys,
Do I need any Pig knowledge to learn Hive? Or understanding Hadoop will

mapper per
file if your files are small. You can control the number of maps by
controlling the split sizes.
Mapred.min.split.size
Mapred.max.split.size

Thanks.

The exceptions seem to be another problem.
They all happened on one node.
And after the task attempts failed at that node,
retried on other nodes and no exceptions.
So that, the exception maybe have nothing to do with the performance issue.
