Eric Hanson created HIVE-4685:
---------------------------------
Summary: query using LIKE does not vectorize, then crashes
Key: HIVE-4685
URL: https://issues.apache.org/jira/browse/HIVE-4685
Project: Hive
Issue Type: Sub-task
Components: Query Processor
Affects Versions: vectorization-branch
Reporter: Eric Hanson
The query
select count(ddate) from factsqlengineam_vec_orc where ddate like "2013%";
Starts up but does not run in vectorization mode. Then during non-vectorized
execution it crashes.
Expected result:
Query runs vectorized and runs successfully.
Actual result:
hive> select count(ddate) from factsqlengineam_vec_orc where ddate like "2013%";
Total MapReduce jobs = 1
Launching Job 1 out of 1
Number of reduce tasks determined at compile time: 1
In order to change the average load for a reducer (in bytes):
set hive.exec.reducers.bytes.per.reducer=<number>
In order to limit the maximum number of reducers:
set hive.exec.reducers.max=<number>
In order to set a constant number of reducers:
set mapred.reduce.tasks=<number>
Validating if vectorized execution is applicable
