Description

given Hive tables:
1) create table pig_hcatalog_1 (si smallint) STORED AS TEXTFILE;
2) create table all100k (si smallint, ti tinyint) STORED ....;

the following sequence of steps (assuming there is data in all100k)

a=load 'all100k' using org.apache.hive.hcatalog.pig.HCatLoader();
b = foreach a generate si;
store b into 'pig_hcatalog_1' using org.apache.hive.hcatalog.pig.HCatStorer();

produces
