Accumulo K/V存储方案

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 Hadoop、Zookeeper 和 Thrift 构建。

Apache Accumulo 1.7.2 发布了，

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
