Apache Accumulo 1.7.2 发布了,Apache Accumulo 是一个可靠的、可伸缩的、高性能的排序分布式的 Key-Value 存储解决方案,基于单元访问控制以及可定制的服务器端处理。使用 Google BigTable 设计思路,基于 Apache HadoopZookeeperThrift 构建。

一些提升:

  • Write-Ahead Logs can be prematurely deleted

  • Upgrading to Apache Commons VFS 2.1

  • Native Map failed to increment mutation count properly

  • Open WAL files could prevent DataNode decomission

  • Remove unnecessary copy of cached RFile index blocks

  • Analyze Key-length to avoid choosing large Keys for RFile Index blocks

  • Minor performance improvements.

其他改变:

  • ACCUMULO-3923 bootstrap_hdfs.sh script would copy incorrect jars to hdfs.

  • ACCUMULO-4146 Avoid copy of RFile Index Blocks when already in cache.

  • ACCUMULO-4155 No longer publish javadoc for non-public API to website. (Still available in javadoc jars in maven)

  • ACCUMULO-4173 Provide balancer to balance table within subset of hosts.

  • ACCUMULO-4334 Ingest rates reported through JMX did not match rates reported by Monitor.

  • ACCUMULO-4335 Error conditions that result in a Halt should ensure non-zero process exit code
