Hortonworks Data Platform (HDP) ver 2
Now leveraging Apache Hadoop 0.23, this public preview release includes:
- Next-generation MapReduce Architecture adds advancements in scalability, performance and High Availability, decouples MapReduce from the resource management architecture and enables new application types to plug into Hadoop, including stream processing, graph processing, bulk synchronous processing and message passing interface (MPI);
- HDFS NameNode High Availability improves data integrity and supports multiple failover options;
- HDFS Federation provides a clear separation of Namespace and Block Storage and improves scalability, isolation and multitenant architectures; and
- Most up-to-date stable Hadoop components including HCatalog, HBase, Hive and Pig.
-- Hortonworks
For those looking for a stable, production-ready version, stick with HDP v1, based on Apache Hadoop 1.0, as it is currently found in large-enterprise deployments.
SolrCloud Phase 2: (Almost) Complete
According to Mark Miller of Lucid Imagination:In Phase 1 we built on top of Solr's distributed search capabilities and added cluster state, central config, and built-in read side fault tolerance. Phase 2 is even more ambitious and focuses on the write side. We are talking full-blown fail tolerance for reads and writes, near real-time support, real-time GFT, true single node durability, optimistic locking, cluster elasticity, improvements to the Phase 1 features, and more.
Once we get Phase 2 into trunk we will work on hardening and finishing a couple missing features-then SolrCloud should be ready to be part of the upcoming Lucene/Solr 4.0 release.
