Michael Echevarria commented on TEIID-4858:
-------------------------------------------
Only difference I can see is the Execution Factory. Simple returns quickly where Hive
takes 30+ seconds.

hive translator is extremely slow
---------------------------------
Key: TEIID-4858
URL: https://issues.jboss.org/browse/TEIID-4858
Project: Teiid
Issue Type: Bug
Components: JDBC Connector
Affects Versions: 8.12.9.6_3
Environment: Tested against JDV 6.3.4 and the Cloudera quickstart 5.8 VM with the
Cloudera sample data loaded into hive
Reporter: Michael Echevarria
Assignee: Steven Hawkins
When querying a table through the hive translator the results take close to 30 seconds to
return.
When querying a table through jdbc default results take under 1 second to return.
Both use the same underlying jboss server datasource.
