0 dead servers
Aggregate load: 1667, regions: 1435

根据你提供的 status 'simple' 命令输出，HBase 集群目前的状态如下：

  • 8 live servers: 有8个区域服务器在运行。
  • 0 dead servers: 没有区域服务器宕机。
  • Aggregate load: 202, regions: 1434: 整体负载为202，共有1434个区域。

每个区域服务器的情况如下（以其中几个为例）：

  • requestsPerSecond: 每个服务器的请求处理速率大约在24至29之间。这表示每秒钟每个服务器处理的请求数量。
  • numberOfOnlineRegions: 每个服务器在线管理的区域数量大致在170至216之间，这影响服务器的工作负荷。
  • usedHeapMB 和 maxHeapMB: 已使用的堆内存与堆内存上限。大部分服务器的已用堆内存超过1000 MB，接近其上限1472 MB。
  • storefileSizeMB 和 memstoreSizeMB: 存储文件大小和内存存储的大小，两者都显示出较高的使用量，这也是压力的一个指标。

这些指标表明，尽管没有服务器宕机，但区域服务器的内存使用接近其上限，处理的区域数量较多，并且处理的请求频率较高。这些因素表明集群负载是相对较高的。如果你经常见到内存接近上限或请求处理速率持续较高，可能需要考虑优化HBase的配置，例如增加区域服务器的数量或优化数据模型和访问模式，以降低单个服务器的压力。
