When I run the below pig codes:
a = load '/logs/2011-03-31';
b = filter a by $1=='a' and $2=='b';
store b into '20110331-ab';
It runs a M/R that have thousands maps, and then create a output store
directory that have the same number so many files.
I have a doubt that how I could store less files when I use pig to store
files in the HDFS.
