Cutting-edge Hadoop clusters are bound to need custom (add-on) services that are not available in the Hadoop distribution of their choice. Agility is crucial for companies to integrate any service into existing large-scale Hadoop clusters with ease.
Apache Ambari manages the Hadoop cluster and solves this problem by extending the stack with add-on services, which can be a new Apache project, different Hadoop file system, or internal tool. This talk covers how to create a service definition in Ambari to manage lifecycle commands and configs, plus advanced topics like packaging, installing from multiple repositories, recommending and validating configs using Service Advisor, running custom commands, defining dependencies on configs and other services, and more. We will also cover how to create custom metrics and dashboards using Ambari Metric System and Grafana, generating alerts, and enabling security by authenticating with Kerberos.
Further, we will discuss the future of service definitions and how Ambari 3.0 will support custom services through Management Packs to enable Hadoop vendors to release software faster.

While some organizations have adopted open stack storage, others are evaluating options like NAS, NFS or other file systems. Oracle Database 12c R1 introduces ACFS as a high availability NFS file system (HANFS) that allows files on ACFS clusters to be accessed outside the cluster using highly available NFS exports, providing continuous access even if the exporting node fails.
Improving the Performance of the qcow2 Format (KVM Forum 2017)Igalia
By Alberto García.
qcow2 is QEMU's native file format for storing disk images. One of its features is that it grows dynamically, so disk space is only allocated when the virtual machine needs to store data. This makes the format efficient in terms of space requirements, but has an impact on its I/O performance. This presentation will describe some of those performance problems and will discuss possible ways to address them. Some of them can be solved by simply adjusting configuration parameters, others require improving the qcow2 driver in QEMU, and others need extending the file format itself.

Storage 101: Rook and Ceph - Open Infrastructure Denver 2019Sean Cohen
Starting from the basics, we explore the advantages of using Rook as a Storage operator to serve Ceph storage, the leading Software-Defined Storage platform in the Open Source world. Ceph automates the internal storage management, while Rook automates the user-facing operations and effectively turns a storage technology into a service transparent to the user. The combination delivers an impressive improvement in UX and provides the ideal storage platform for Kubernetes.
A comprehensive examination of use cases and open problems will complement our review of the Rook architecture. We will deep-dive into what Rook does well, what it does not do (yet), and what trade-offs using a storage operator involves operationally. With live access to a running cluster, we will showcase Rook in action as we discuss its capabilities.

Most of you know that SLES was the only supported OS for SAP HANA few years back. But for quite sometime, Red Hat Enterprise Linux for SAP HANA 6.5 is certified minimum version available for productive usage, which is based on Intel IvyBridgeEX (Xeon E7 v2) CPU architecture.
I was working with SLES since Nov'2009 and installed SAP HANA 1.0 built 5 for the first time. Due to other commitments, I was not looked into RHEL part till Dec'2014. Remotely, from Bangalore, I was working hands-on with RHEL colleagues on their Lab through their OPEN program and that's why collected some basic knowledge on this.

must decide if the setup failback or register the old Primary as the new secondary before HANA
System Replication can start again
14. RED HAT CONFIDENTIAL14
Failover Scenario – What if
“AUTOMATED_REGISTER = True”
∙ Wait for “DUPLICATE_PRIMARY_TIMEOUT” timeout
