Greetings all, It gives me great pleasure to announce that the Apache Hadoop community has voted to release Apache Hadoop 3.2.0.
Apache Hadoop 3.2.0 is the first release of Apache Hadoop 3.2 line for the year 2019, which includes 1092 fixes since previous Hadoop 3.1.0 release. Of these fixes: - 230 in Hadoop Common - 344 in HDFS - 484 in YARN - 34 in MapReduce Apache Hadoop 3.2.0 contains a number of significant features and enhancements. A few of them are noted as below. - ABFS Filesystem connector : supports the latest Azure Datalake Gen2 Storage. - Enhanced S3A connector : including better resilience to throttled AWS S3 and DynamoDB IO. - Node Attributes Support in YARN : helps to tag multiple labels on the nodes based on its attributes and supports placing the containers based on expression of these labels. - Storage Policy Satisfier : supports HDFS (Hadoop Distributed File System) applications to move the blocks between storage types as they set the storage policies on files/directories. - Hadoop Submarine : enables data engineers to easily develop, train and deploy deep learning models (in TensorFlow) on very same Hadoop YARN cluster. - C++ HDFS client : helps to do async IO to HDFS which helps downstream projects such as Apache ORC; - Upgrades for long running services : supports in-place seamless upgrades of long running containers via YARN Native Service API and CLI. * For major changes included in Hadoop 3.2 line, please refer Hadoop 3.2.0 main page [1]. * For more details about fixes in 3.2.0 release, please read the CHANGELOG [2] and RELEASENOTES [3].
