As Apache Hadoop adoption continues to advance, customers are depending more and more on Hadoop for critical tasks, and deploying Hadoop for use cases with more real-time requirements. In this session, we will discuss the desired performance characteristics of such a deployment and the corresponding challenges. Leave with an understanding of how performance-sensitive deployments can be accelerated using In-Memory technologies that merge the Big Data capabilities of Hadoop with the unmatched performance of In-Memory data management.

Transcript

  • 1. In-Memory Accelerator for Hadoop™ www.gridgain.com #gridgain
  • 2. Hadoop: Pros and Cons What is Hadoop? Pros: > Hadoop is a batch system > Scales very well > HDFS - Hadoop Distributed File System > Fault tolerant and resilient > Data must be ETL-ed into HDFS > Very active and rich eco-system > Parallel processing over data in HDFS > Process TBs/PBs in parallel fashion > Hive, Pig, HBase, Mahout... > Most popular data warehouse Cons: > > Complex deployment > Significant execution overhead > www.gridgain.com Batch oriented - real time not possible HDFS is IO and network bound Slide 2
  • 3. In-Memory Accelerator For Hadoop: Overview Up To 100x Faster: 1. In-Memory File System 100% compatible with HDFS Boost HDFS performance by removing IO overhead Dual-mode: standalone or caching Blend into Hadoop ecosystem 2. In-Memory MapReduce Eliminate Hadoop MapReduce overhead Allow for embedded execution Record-based www.gridgain.com Slide 3
  • 4. GridGain: In-Memory Computing Platform www.gridgain.com Slide 4
  • 5. In-Memory Accelerator For Hadoop: Details > PnP Integration Minimal or zero code change > Any Hadoop distro Hadoop v1 and v2 > In-Memory File System 100% compatible with HDFS Dual-mode: no ETL needed, read/write-through Block-level caching & smart eviction Automatic pre-fetching Background fragmentizer On-heap and off-heap memory utilization > In-Memory MapReduce In-process co-located computations - access GGFS in-process Eliminate unnecessary IPC Eliminate long task startup time Eliminate mandatory sorting and re-shuffling on reduction www.gridgain.com Slide 5
  • 6. GridGain Visor: Unified DevOps File Manager HDFS Profiler www.gridgain.com Slide 6
  • 7. Benchmarks: GGFS vs HDFS 10 nodes cluster of Dell R610 > > Ubuntu 12.4, Java 7 > 10 GBE network > www.gridgain.com Each has dual 8-core CPU Stock Apache Hadoop 2.x Slide 7
  • 8. Comparison: Hadoop Accelerator vs. Spark > No ETL required > Automatic HDFS read-through and write-through Data is loaded on demand > Per-block file caching Changes to data do not get propagated to HDFS Explicit ETL step consumes time > Only hot data blocks are in memory > Strong management capabilities GridGain Visor - Unified DevOps www.gridgain.com Requires data ETL-ed into Spark Needs to have full file loaded If does not fit - gets offloaded to disk > No management capabilities Slide 8
  • 9. Customer Use Case: Task & Challenge Task: Challenge: > Real time search with MapReduce > Hadoop MapReduce too slow (> 30 sec) > Dataset size is 5TB > Data scanning slow due to constant IO > Writes 80%, reads 20% > Overall job takes > 1 minute > Perceptual real time SLA (few seconds) www.gridgain.com Slide 9
  • 10. Customer Use Case: Solution > Utilize existing servers Start GridGain data node on every server > Only put highly utilized files in GGFS User controlled caching > In-Memory MapReduce over GGFS Embedded processing > Results under 3 seconds www.gridgain.com Slide 10
