Consolidating files logic 9
The map phase counts the words in each document, then the reduce phase aggregates the per-document data into word counts spanning the entire collection.
as much as I love Logic, it's So, you've finished composing, recording, arranging, mixing and mastering your song/music in Logic. Well, you could play your finished music tracks in Logic...One rule of thumb is that everything you can hear from Logic's Stereo 1-2 output channel will appear in your exported audio file. command will only allow you to export selections to a MIDI file and tracks to individual audio files.So now is a good time to mute any tracks or regions you don't want in your final mix! So if you have 10 tracks in your project then those 10 tracks will be exported to 10 corresponding audio files.Let's take a look at how it works and when you should use it.The trouble with sorting is that it is such a nice neat subject that it is all too tempting to get carried away with the theoretical niceties and go for the fastest most elegant and perhaps the most recent.The job configuration supplies map and reduce analysis functions and the Hadoop framework provides the scheduling, distribution, and parallelization services. A job usually has a map and a reduce phase, though the reduce phase can be omitted.
For example, consider a Map Reduce job that counts the number of times each word is used across a set of documents.
This is only true if you can read the entire data set into memory.
In short most of the sorting methods that you come across are in memory methods - what would have been called in core methods in the old days of magnetic core memory!
There is nothing more fascinating than trying to figure out just exactly how quick sort, heap sort etc.
work but all of these methods assume that you have fast direct access to each item of data.
For a complete discussion of the Map Reduce and the Hadoop framework, see the Hadoop documentation, available from the Apache Software Foundation at chapter covers the following topics: Apache Hadoop Map Reduce is a framework for processing large data sets in parallel across a Hadoop cluster.
