Scale issues have gone from being about sheer volume of traffic such as those from of IOT led DDoS attacks or even the diversity of traffic you get from a high variety of device types, but also from the need for absolute speed to nip things in the bud and catch things before they become a problem. With this, it creates a massive long tail problem – a huge amount of data ... Read More

Feed: Hadoop – Cloudera Engineering Blog. Author: Justin Kestelyn. Understanding how checkpointing works in HDFS can make the difference between a healthy cluster or a failing one. Checkpointing is an essential part of maintaining and persisting filesystem metadata in HDFS. It’s crucial for efficient NameNode recovery and restart, and is an important indicator of overall cluster health. However, checkpointing can also be a source of confusion for operators of Apache Hadoop clusters. In this post, I’ll explain the purpose of checkpointing in HDFS, the technical details of how checkpointing works in different cluster configurations, and then finish with a set ... Read More

Feed: Hadoop – Cloudera Engineering Blog. Author: Sandy Ryza. Thanks to the improvements described here, CDH 5 will ship with a version of MapReduce 2 that is just as fast (or faster) than MapReduce 1. Performance fixes are tiny, easy, and boring, once you know what the problem is. The hard work is in putting your finger on that problem: narrowing, drilling down, and measuring, measuring, measuring. Apache Hadoop is no exception to this rule. Recently, Cloudera engineers set out to ensure that MapReduce performance in Hadoop 2 (MR2/YARN) is on par with, or better than, MapReduce performance in Hadoop ... Read More
