Subject why hive ignore my setting about reduce task number?
Date Wed, 12 May 2010 12:22:27 GMT
In hive-default.xml I have set reduce task num is 20. But the hive ignore my
setting in second job .

Here is hive log, 


Total MapReduce jobs = 2

Launching Job 1 out of 2

Number of reduce tasks not specified. Defaulting to jobconf value of: 20

Launching Job 2 out of 2

Number of reduce tasks determined at compile time: 1


The num of reduce tasks in first job is 20.

But the second job ignore my setting, determined by compiler.

How can set all the reduce task to number 20?
