------------------------------------

             Summary: HCatStorer throws ClassCastException while storing tinyint/smallint
data
                 Key: HIVE-6724
                 URL: https://issues.apache.org/jira/browse/HIVE-6724
             Project: Hive
          Issue Type: Bug
          Components: HCatalog
    Affects Versions: 0.12.0
            Reporter: Eugene Koifman
            Assignee: Eugene Koifman


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
