以下是HBase中HMaster线程调用的攻略:
1. HMaster线程的作用
HMaster是HBase的主节点,它负责管理整个集群的元数据和协调RegionServer的工作。HMaster线程是HMaster节点上的一个线程,它负责处理HBase集群中的各种请求和操作。
2. HMaster线程的启动
HMaster线程是在HMaster节点上启动的。当HMaster节点启动时,它会启动HMaster线程,并开始监听来自客户端和RegionServer的请求。
以下是HMaster线程启动的示例代码:
“`java
public class HMaster extends Thread {
private final Configuration conf;
private final ServerName serverName;
private final ServerManager serverManager;
private final MasterServices services;
public HMaster(Configuration conf, ServerName serverName, MasterServices services) {
this.conf = conf;
this.serverName = serverName;
this.services = services;
this.serverManager = new ServerManager(services);
}
