Affects Version/s: Impala 0.6
Fix Version/s: Product Backlog
Environment:OS: Red Hat Enterprise Linux Server release 5.5 (Tikanga)
CPU: Intel(R) Core(TM) i5-2400 CPU @ 3.10GHz
I'm testing impala on an environment with 5 nodes. Following sql always fails on 3 of the 5 nodes:
SELECT device_model, COUNT FROM rps__h_data_partition_log GROUP BY device_model ORDER BY device_model LIMIT 50;
Table rps__h_data_partition_log haves 200000+ records.
The difference I can find of these 3 nodes is cpu type.
3 nodes are using Intel Core i5. The other 2 are using Intel Core2 Quad CPU.
The group by query always fail on these 3 i5 nodes which will cause jvm crash. If I stop the 3 nodes impala service, the query can be finished on the other 2 nodes.
