Whether you are a Bright customer, a Bright reseller, or in the process of evaluating Bright, you will be aware that Bright Cluster Manager is great at monitoring your cluster. From the moment that you set up your cluster for the first time, Bright’s monitoring capabilities set to work, providing comprehensive metrics and alerts.Read More >
If you are responsible for managing a cluster, you certainly use monitoring software to help you keep it running right. Many organizations, however, tend to lump cluster monitoring with cluster health checks, as if they were one and the same, interchangeable. They’re not.
One way to look at it is that cluster monitoring involves tracking and measuring data. Health checks show how well things are working (diagnostic).Read More >
From the components that comprise a node (e.g., CPU cores plus accelerators and coprocessors, memory, disks), to the operating system and HPC software stack (e.g., client system for executing workload), device-specific metrics abound. As individual nodes communicate via interconnect fabrics (e.g., Ethernet, InfiniBand), metrics mushroom to reveal cluster-wide perspectives.
Everyone involved in running HPC clusters needs metrics. Hybrid-architecture, distributed systems, however, are a challenge to monitor, especially as systems scale out. Given the importance and inherent difficulties, it is not surprising that monitoring is once again topical in the HPC community. In fact, recent discussions are calling for an extreme makeover, by expressing the need to modernize monitoring for HPC clusters.Read More >
Last week we released support for Apache Hadoop 2.5.0. I thought it would be a good time to revisit all the updates we’ve made over the last 6 months - in case you missed them.
Our latest updates include:
- Apache Hadoop 2.5.1 Typo? Not exactly. We introduced support for Apache Hadoop 2.5.0 last week. Since Version 2.5.1 (released on September 13, 2014) is a minor release that builds upon the stable 2.4.1 release, you can now expect support via YUM updates to Bright. Note that vanilla Apache Hadoop includes HDFS (the Hadoop Distributed File System), ZooKeeper (the coordination service) as well as YARN (the workload manager).
- Cloudera CDH 5.1.0 We introduced support for CDH 5.1.0 in mid-July.
- Hortonworks HDP 2.1 We introduced support for Hortonworks Data Platform (HDP) 2.1 in mid-May.
Bottom line: Bright Cluster Manager maintains support for all major distributions of Apache Hadoop. Because we’re obsessed with keeping you current, you don’t have to be. We free you up to focus on the analysis of Big Data - and wasn’t that why you got interested in Hadoop in the first place?Read More >
