By Sean Owen, Sandy Ryza, Uri Laserson, Josh Wills

During this sensible publication, 4 Cloudera facts scientists current a suite of self-contained styles for appearing large-scale info research with Spark. The authors deliver Spark, statistical equipment, and real-world facts units jointly to coach you ways to procedure analytics difficulties through example.

You'll begin with an creation to Spark and its atmosphere, after which dive into styles that practice universal techniques—classification, collaborative filtering, and anomaly detection between others—to fields similar to genomics, safety, and finance. when you have an entry-level realizing of desktop studying and facts, and also you application in Java, Python, or Scala, you'll locate those styles valuable for engaged on your personal info applications.

Patterns include:
- Recommending tune and the Audioscrobbler information set
- Predicting wooded area conceal with determination trees
- Anomaly detection in community site visitors with K-means clustering
- realizing Wikipedia with Latent Semantic Analysis
- reading co-occurrence networks with GraphX
- Geospatial and temporal facts research at the manhattan urban Taxi journeys data
- Estimating monetary chance via Monte Carlo simulation
- studying genomics information and the BDG project
- examining neuroimaging info with PySpark and Thunder

Sample text

The id type is defined as a C structure (with no access control) containing just the pointer to the class, so you can read it just as you would any other field in a structure. Doing this is strongly discouraged. Objective-C objects may forward messages, and the object pointer that you have might be a proxy. If you want to get another object’s class, you should send it a -class message instead. This is slower, but it won’t break in the presence of proxies. You can test whether an object is a proxy by sending it an -isProxy message, but if you’re sending one message anyway, you may as well just send one to get the class.

This is how you call methods that you have overridden. Sending messages to super uses a different method lookup function that takes a pointer to an objc_super structure as the argument. This structure contains both the target class and the target object. 45 46 CHAPTER 2: An Objective-C Primer The superclass is fixed at compile time. When you compile an Objective-C class, all messages to super will be looked up on the class that is defined as the superclass in the class interface. For most code, this doesn’t matter, but it’s something that you need to remember if you are using the runtime library functions to add methods to a class.

Now, with the non-fragile ABI, you can hide private instance variables from the subclasses. Every reference to them goes via an indirection layer. The offset is now a variable, not a compile-time constant. By default, Objective-C instance variables are protected, meaning that they are only accessible by the class or its subclasses. If you prefix them 29 30 CHAPTER 2: An Objective-C Primer with @private they are only available to the class, and with @public they are accessible anywhere. This is quite uncommon.
