At StampedeCon 2012 in St. Louis, Pritam Damania presents: Reliable backup and recovery is one of the main requirements for any enterprise grade application. HBase has been very well embraced by enterprises needing random, real-time read/write access with huge volumes of data and ease of scalability. As such, they are looking for backup solutions that are reliable, easy to use, and can co-exist with existing infrastructure. HBase comes with several backup options but there is a clear need to improve the native export mechanisms. This talk will cover various options that are available out of the box, their drawbacks and what various companies are doing to make backup and recovery efficient. In particular it will cover what Facebook has done to improve performance of backup and recovery process with minimal impact to production cluster.

The document outlines operational requirements for enhancing BGP error handling. It notes that current NOTIFICATION-based error handling causes disproportionate failures in service provider networks. The requirements are to: 1) Avoid sending NOTIFICATIONS where possible to prevent session teardown, 2) Recover RIB consistency after invalid updates, and 3) Allow session reset while maintaining forwarding. It also calls for improved monitoring capabilities. The draft has received support from operational forums and the author seeks WG adoption.
The document discusses configuration of a MapR cluster, including setting up node topology, volumes, central configuration, multiple network interface cards (NICs), virtual IPs for NFS high availability, managing users, and permissions. It provides guidance on configuring these aspects of the MapR cluster and explains objectives like setting replication levels and quotas for volumes.
High availability (HA) aims to ensure a prearranged level of operational performance by increasing the mean time between failures (MTBF) and decreasing the mean time to repair (MTTR). When implementing HA for a DMF system, considerations include redundant hardware, limiting single points of failure, minimizing downtime during repairs and upgrades, and having mechanisms to quickly address failures like STONITH (shoot the other node). Real-world HA often involves initially setting up a single DMF server and testing it before converting to an active-passive HA configuration with mechanisms to monitor the system and quickly transition services between nodes if needed.
Strata + Hadoop World 2012: HDFS: Now and FutureCloudera, Inc.

This document summarizes Google's infrastructure for distributed data storage and processing.
It describes Google File System (GFS), which scales to thousands of servers through replication and partitioning files into chunks distributed across servers. GFS uses a master/slave architecture and optimizes for large reads and writes of append-only files.
It also describes MapReduce, Google's programming model for distributed data processing. MapReduce allows parallelization through a map function that processes key-value pairs, followed by an optional combine and a reduce function to aggregate results. This provides fault tolerance and allows computation to move to data.
The document discusses the functional verification of the Jaguar x86 low-power core. It describes Jaguar's microarchitecture, which includes improvements over the previous Bobcat core such as a new shared L2 cache and updated ISA support.

BGP is used to exchange routing and reachability information among autonomous systems on the internet. It uses TCP port 179 to establish peering sessions between neighbors. Path selection is based on attributes like weight, local preference, origin type, AS path length, IGP metrics, and eBGP relationships. The configuration example shows BGP configured between three routers in different autonomous systems to exchange routing updates.
Facebook uses HBase running on HDFS to store messaging data and metadata. Key reasons for choosing HBase include high write throughput, horizontal scalability, and integration with HDFS. Typical clusters have multiple regions and racks for redundancy. Facebook stores small messages, metadata, and attachments in HBase, while larger messages and attachments are stored separately. The system processes billions of read and write operations daily and continues to optimize performance and reliability.

Norman Maurer discusses how to build low-cost master/slave clusters on Linux using Linux-HA (Heartbeat and DRBD) to provide high availability for mission critical services. Linux-HA allows configuring clusters that can failover services between nodes to ensure availability. DRBD replicates data between nodes, while Heartbeat monitors nodes and fails over services if needed. Configuring DRBD, Heartbeat, and associated scripts allows building clusters for services like Apache HTTPD, databases, mail servers, and more.
This document provides an overview and deep dive into Robinhood's RDS Data Lake architecture for ingesting data from their RDS databases into an S3 data lake. It discusses their prior daily snapshotting approach, and how they implemented a faster change data capture pipeline using Debezium to capture database changes and ingest them incrementally into a Hudi data lake. It also covers lessons learned around change data capture setup and configuration, initial table bootstrapping, data serialization formats, and scaling the ingestion process. Future work areas discussed include orchestrating thousands of pipelines and improving downstream query performance.
The document discusses different architecture options for DECADE, a content distribution system. It considers placing DECADE servers inside data centers or distributed at the network edge. While edge placement has advantages like low latency, it raises challenges around data deduplication across servers. The document then proposes a decoupled architecture where DECADE access is separated from data management through status servers and data servers. This could help address issues like guaranteed data availability times and efficient resource utilization across servers.
The document discusses NameNode high availability (HA) in Cloudera Distribution Hadoop (CDH) 4. It introduces an active-standby approach with a hot standby NameNode that has most of the state of the active NameNode. ZooKeeper and a ZooKeeper Failover Controller (ZKFC) enable automatic failover between the NameNodes. The ZKFC monitors heartbeats and manages ZooKeeper sessions and elections to transition the standby NameNode to the active role when needed.
The document discusses IBM's PowerVM virtualization technology. It describes how PowerVM allows a single physical server to be divided into multiple logical partitions (LPARs), each with dedicated or shared CPUs and memory. It also discusses micro-partitioning which divides physical CPUs into smaller virtual CPUs that can be allocated in fractions to LPARs. The document further explains how LPARs can share physical I/O adapters through virtual I/O servers and how live partition mobility allows moving running LPARs between physical servers without downtime.

This reference architecture document describes deploying the VMware vCloud Enterprise Suite on the IBM PureFlex System hardware platform. Key points:
- The vCloud Suite software provides components for managing and delivering cloud services, while the IBM PureFlex System provides an integrated hardware platform in a single chassis.
- The reference architecture focuses on installing the vCloud Suite management components as virtual machines on an ESXi host to manage consumer resources.
- The IBM PureFlex System provides servers, networking, and storage in a single chassis that can then be easily scaled out. This standardized deployment accelerates provisioning of cloud infrastructure.
- Deployment considerations cover systems management using IBM Flex System Manager, server, networking, storage configurations
