Subject Defining the CORR(X, Y) UDAF in version 0.5
Date Tue, 30 Nov 2010 03:23:38 GMT
I am interested in using the correlation UDAF available in version 0.7 (see but am using  AWS Elastic
Map-Reduce which is currently running version 0.5.

Is there a way to install this function in a older version of Hive?

If not, can anyone suggest an alternative way to implement a correlation
function in 0.5?
