§ Platform Symphony creates a shared, scalable, and fault-tolerant infrastructure, delivering faster, more reliable application performance while reducing cost. What is Platform Symphony ? § Platform Symphony distributes and virtualizes compute-intensive application services and processes across existing heterogeneous IT resources. Node Distributed metadata feature eliminates any single point of failure (metadata is replicated just like data) Should load all the metadata in memory to work Metadata doesn't need to get read into memory before the filesystem is available Dealing with small numbers of large files only dealing with large numbers of any files size and enables mixing of multiple storage types, support write-intensive applications Allows concurrent read but only one writer Allows concurrent read and write by multiple programs No Policy-based archiving: data can be migrated automatically to tapes If nobody has touches it for a given period (So as the data ages, it is automatically migrated to less-expensive storage) so, standard applications cannot use it IBM GPFS file system (GPFS-FPO) Any application can access and use it using all the commands used in Windows/Unix Should define the size of disk space allocated to HDFS No need to define the size of disk space allocated to GPFS filesystems Does not handle security/access control Support access control on file and disk level Does not replicate metadata, has a single point of failure in the Name. Hadoop file system (HDFS) HDFS files can only access with Hadoop APIs.

YARN itself monitors the health of 'YARN containers' hosting parts of the deployed application YARN notifies the Slider manager application of container failure Slider then asks YARN for a new container, into which Slider deploys a replacement for the failed component, keeping the size of managed applications consistent with the specified configuration Slider implements all its functionality through YARN APIs and the existing application shell scripts The goal of the application was to have minimal code changes and impact on existing applications SLIDER (SUPPORT LONG-RUNNING DISTRIBUTED SERVICES) YARN resource management and scheduling works well for batch workloads, but not for interactive or real-time data processing services Apache Slider extends YARN to support long-running distributed services on an Hadoop cluster, Supports restart after process failure, support Live Long and Process (LLAP) Applications can be stopped then started This enables best-effort placement close to the previous locations The distribution of the deployed application across the YARN cluster is persisted Applications which remember the previous placement of data (such as HBase) can exhibit fast start-up times from this feature. For each job, one slave node will act as the Application Master, monitoring resources/tasks, etc. Reduce): each cluster has a Resource Manager, and each data node runs a Node Manager. Tracker YARN (it is the newer version of Map. Tracke: exists on cluster's nodes to receive the orders from Job. Trackes who are nearest to the data as possible. Tracker : receive client applications jobs and send orders to the Task. Reduce v 1 : an implementation for large-scale data processing. Hadoop HDFS : § where Hadoop stores data § a file system that spans all the nodes in a Hadoop cluster § links together the file systems on many local nodes to make them into one large file system that spans all the data nodes of the cluster Hadoop Map. It then transfers packaged code into nodes to process the data in parallel. Hadoop splits files into large blocks and distributes them across nodes in a cluster. Apache Hadoop Stack The core of Apache Hadoop consists of a storage part, known as Hadoop Distributed File System (HDFS), and a processing part which is a Map.
