Subject number of maptasks of hive
Date Mon, 18 Jul 2011 05:25:43 GMT
Does hive split input table file according the ways hadoop provides which a
file is splitted by block size? Then the number of map tasks is decided by
the split size.

But I have a table file which  size is 196MB,my hdfs block size is 64MB,but
I only see 3 map tasks in my web interface.What is the reason?
