-------------------------------------
Summary: Using select columns vs. select * results in long running
query
Key: HIVE-11454
URL: https://issues.apache.org/jira/browse/HIVE-11454
Project: Hive
Issue Type: Bug
Components: JDBC
Affects Versions: 0.13.1
Reporter: Steven Hawkins
Originally logged as https://issues.jboss.org/browse/TEIID-3580
When using the JDBC jars for Hive 0.13.1 running on HDP 2.1, some queries
executed against table 'default.sample_07' takes approximately 20-30 seconds to
return.
The Hive JDBC jars for version 0.13.1 can be found here :
https://github.com/vchintal/hive-jdbc-jars-archive
"SELECT g_0.code, g_0.description, g_0.total_emp, g_0.salary FROM sample_07 AS
g_0" run from a standalone JDBC project results in a 20+ second delay. However
"SELECT * FROM sample_07" has no delay. The same 500 are returned either way.
