Hadoop runs on commodity servers and can scale up to support thousands of hardware nodes. Its file system is designed to provide rapid data access across the nodes in a cluster, plus fault-tolerant capabilities so applications can continue to run if individual nodes fail. Those features helped ...
Hadoop Hardware Vendor: If you have decided to deploy Hadoop, Iron provides hardware platform that is pre-tested and certified. Even though Hadoop runs on commodity hardware, it is important that you work with Iron to ensure the cluster is engineered properly for Hadoop and you get specialized ...
Mahout Algorithms include many new implementations built for speed on Mahout-Samsara. They run on Spark and some on H2O, which means as much as a 10x speed increase. You’ll find robust matrix decomposition algorithms as well as a Naive Bayes classifier and collaborative filtering. The new spa...
With the linear model and logistic regression performed in the previous sections, you have seen a taste of high-performance analytics on the Hadoop platform. You are now ready to continue with the RevoScaleR Distributed Computing Guide, which continues the analysis of the 2012 airline on-time ...
Since Hadoop is an open-source platform that runs on proper industry-standard hardware, it is a highly scalable platform wherein distinct nodes can easily be united in the system for making replicas of data blocks. 3. Fault-tolerant In Hadoop, data is actually saved inHDFSwherein it can aut...
The web UI runs on the name node, on port 50070 (by default). That port is exposed by the hadoop-succinctly Docker container, which means you can browse to http://127.0.0.1:50070/explorer.html (substitute 127.0.0.1 with the IP address of your Docker VM if you're using Mac or Win...
The second key area is Windows Azure support for virtual machines (VMs) running Linux. Hadoop runs on top of Linux and leverages Java, which makes it possible to set up your own single-node or multi-node Hadoop cluster. This can be a tremendous money saver and productivity booster, because...
