UK minimization J is not easy, but we can take an iterative approach: fixing the UK first, choosing the best rnk, is easy to see, as long as the data points are classified to the nearest center of his and the J-minimum can be guaranteed. The next step is to fix the RNK and then find the best UK. If J is derivative of the UK

directly put into the output scheme set. If the read scheme does not have a specified attribute value, it will add all the possible schemes after this attribute value is added to the output scheme set.
The extension of the room number attribute only needs to be done once before the first "Inter-object constraint" is applied.
Use the constraints between objects to filter the extended solution set and remove the solution that does not meet the constraints. The final answer is obtained. The deriva

Set Environment Variables
Before hadoop is started, three files need to be configured.
However, before that, we need to set several environment variables similar to Windows to facilitate command-line.
Export hadoop_home =/users/Billy/hadoop
Export Path = $ path: $ hadoop_home/bin
Configure hadoop-env.sh
Under the hadoop-> conf directory, locate the hadoop-env.sh and open the Edit to make the following settings:
Export java_home =/library/Java/Home (remove comments)

This article describes in detail the four attributes of constraints: Deferrable/not deferrable, Deferred/immediate, enalbe/disable, validate/novalidate, and how to apply these attributes to cope with related problems.
1. Deferrable, not deferrable (default value)
