Steven Hawkins commented on TEIID-4858:
---------------------------------------
There is no known case where Teiid/EAP behaves differently when accessing a Hive source
vs. just going through JDBC. You will need to ensure you are executing the exact same
source query either way and that you are using the same libraries etc.
If you think that you are seeing difference the first thing to do is to isolate the EAP
DataSource to compare vs direct JDBC - more than likely any issue would be at that layer
rather than with Teiid.
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.
