在Java客户端中关闭后，HBase本地群集无法启动
我有一个用Java7编译的Maven项目，它使用SpringIOC来测试hbase客户机jar中的使用 依赖项如下所示：在Java客户端中关闭后，HBase本地群集无法启动,java,spring,maven,hadoop,hbase,Java,Spring,Maven,Hadoop,Hbase,我有一个用Java7编译的Maven项目，它使用SpringIOC来测试hbase客户机jar中的使用 依赖项如下所示： <dependency> <groupId>org.apache.hbase</groupId> <artifactId>hbase-client</artifactId> <version>1.0.0-cdh5.5.4</version> </dependenc

为什么要运行HBase群集两次？HBase即使在测试中也不常见。为什么不只运行一次HBase，测试所有您想要的并最终关闭它？因为测试将检查我的重新连接机制是否工作，即使群集变得不可用，然后再次可用..而且我的客户端不会失去连接。为什么要运行两次HBase群集？HBase即使在测试中也不常见。为什么不只运行一次HBase，测试所有您想要的，并最终关闭它？因为测试将检查我的重新连接机制是否工作，即使群集变得不可用，然后再次可用..而且我的客户端不会失去连接。
