在本快速入門中,您會使用 Azure Resource Manager 範本 (ARM 範本),在 Azure HDInsight 中建立Apache Hadoop叢集。 Hadoop 是原始的開放原始碼架構,用於分散式處理和分析叢集上的巨量資料集。 Hadoop 生態系統包含相關的軟體和公用程式,其中包括 Apache Hive、Apache HBase、Spark、Kafka 等等。
resource manager HA是hadoop自从2.4之后推出的功能,以Active/Standby的方式提供冗余,目的是为了消除单点失败的风险。 1、总体架构: 2、故障切换:有自动和手动两种形式。 手动:如果以手动形式切换,使用yarn haadmin命令首先将Active节点转为standby,再将standby节点转为active。
