Description
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>
