Thanks Yexi , But how it can be accomplished. The input to Desicion Tree MR will be a set of data. But while predicting a data it will be a one line data without classlabel right? So what changes will be there in mrjob.Should we design like this. 1. When a set of data is coming draw Desicion tree 2. else if a one line data is coming.check the output of decision tree(Decision tree generated from mr) and predict the class label.
------- M1_train - dataset for training. M1_test - test data or prediction. 1. Will it be one data as input for prediction or set of data given as input at-once. 2.we also need to ensure in our pgm that M1_test belongs to M1_train only. we shld check that also ...right? if M1_test is given into M2_train it should show error. is nt 'it?. Pls suggest if my thoughts are wrong.
