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