HBase 在核心库中有自己的 java 客户端。它几乎涵盖了所有内容。 (也有连接)。如果您需要异步客户端,您可以从 stumbleupon 查看 asyncbase,这是一个可靠的客户端。但它的过滤器支持是有限的。(尽管它有基本的过滤器,而且它们的工作方式很神奇)。如果您使用java,我不建议使用via rest。
HBase has its own java client in core library. It covers pretty much everything. (Got connection as well). If you need a asynchronous client You can check asyncbase from stumbleupon, which is a solid client. But it's filter support is limited.(it has basic filters though, and they work like charm). If you are using java I wouldn't recommend using via rest.
昆德拉是推荐客户使用的。
作者正在为此努力。
Kundera is a recommend client for use.
the author is work hard for it.
Kundera 是 Hbase 以及 Cassandra 和 MongoDB 的对象数据存储映射工具。
一些显着的功能包括:

playOrm 是另一个 java 工具,您可以在其中注释实体并立即启动并运行。它故意不符合 JPA,因为 nosql 太不同了。它有像 findAll() 这样的方法,因为你想在 nosql 中并行读取。
playOrm 确实添加了 JQL,但对 nosql 做了一些改动...作为改动的一个示例,您可以将一万亿行划分为 10 亿个分区,并对任何分区执行 JQL 并与其他表连接。如果您来自 JPA 领域,那么它会让您更轻松地过渡到 noSql。
playOrm is a another java tool where you can annotate your entities and immediately be up and running. It is NOT JPA compliant on purpose as nosql is too different. It has methods like findAll() as you want to parallel your reads in nosql.
playOrm does add JQL but with a twist for nosql....As an example of the twist, you can partition a trillion row into 1 billion partitions and do JQL into any partition and join with other tables. It makes a transition to noSql much easier if you come from the JPA world.
HBaseExecutor,HBase Java 客户端的简单包装。与原生 HBase Java 驱动程序相比,HBaseExecutor 具有以下功能:
这是一个使用 HBaseExecutor 的简单示例,
与使用 HBase Java 客户端的示例进行比较:(
