table1 = load 'mytable' using org.apache.hcatalog.pig.HCatLoader();
table2 = sample table1 0.01;
store table2 into 'table2' using org.apache.hcatalog.pig.HCatStorer();
table3 = filter table2 by a > 10;
store table3 into 'table3' using org.apache.hcatalog.pig.HCatStorer();
I find that table3's data is not from table2.
because every 'store' is from beginning. and sample is random,so the result
is different.
so can I use some function to make that table3's data is from table2.,is
there some sample seeds in pig?
