when exec hive query throw exception as follow
I donnot know where is error log I found $HIVE_HOME/ logs not exist

Total MapReduce jobs = 1
Launching Job 1 out of 1
Number of reduce tasks not specified. Estimated from input data size: 3
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>
Cannot run job locally: Input Size (= 2304882371) is larger than
hive.exec.mode.local.auto.inputbytes.max (= 134217728)
