The pig script should be as easy as hive_table = LOAD ‘a_table’ USING org.apache.hcatalog.pig.HCatLoader(); hive_column = FOREACH hive_table GENERATE a_column;
The trickier part could be the pig infrastructure. You can try just running the script with -useHCatalog. You may need to register the hcat jars, too.

In pig, how can I execute this command 'select a_column from a_table' through HCatalog? Any guidance is appreciated. Patcharee
