Hi, all:
I am a newbie to hive.
When I excute command (select count(*) from log where end_clock =
'2012-02-14_08'; ) in hive, it is OK.
While I excute command (select count(*) from log where end_clock >=
'2012-01-18_08' and end_clock <= '2012-02-14_08';) in hive, it report
the following error:
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>
java.lang.ArithmeticException: / by zero
