In this post we will review the more important aspects related to RDD checkpointing. We will continue working on the over500 RDD we created in the previous post on caching. You will remember that checkpointing is a process of truncating an RDD’s lineage graph and saving its materialized version on a persistence store.
Spark offers developers two simple and quite efficient techniques to improve RDD performance and operations against them: caching and checkpointing. Caching allows you to save a materialized RDD in memory, which greatly improves iterative or multi-pass operations that need to traverse the same data set over and over again (e.g. in machine learning algorithms.)
Last week I completed development of our 2 day class teaching Apache Spark which will be integrated in our Big Data and Data Science classes after the QA cycle. I will be feeding some fragments of the material with additional comments and notes that would help you get a taste of what the new content is all

Big Hadoop distros, like Cloudera’s CDH and Hortonworks’ HDP that bundle Spark, have varying degree of support for R. For the time being, CDH decided to opt out of supporting R (their latest CDH 5.8.x version does
The Spring framework has been a highly popular framework for Java applications. So popular in fact, it is pretty much the defacto standard of Java application frameworks.

A few months ago I wrote about how our core Java courses are being updated to Java 8. Now that the updates are a little further along we also have a course map that can show which Java 8 courses we have might be appropriate for you. You can find that here: Java Course Map
ASP.NET MVC provides several HTML helper functions that generates HTML automatically. E.g. Html.TextBox, Html.CheckBox etc. We can also create our own custom helper functions as well. For creating HTML functions following steps have to be performed: 1. Create a static class 2. Add a static method that returns either string or MvcHtmlString 3. First Parameter
Both SharePoint 2016 and Project Server 2016 Release Candidate are not available. SharePoint 2016 RC is mostly feature complete and it’s now safe enough to evaluate it to get an overall picture of the final product. If you have older Beta 2 then it can be upgraded to RC.
