Namenodes 在 HA 集群上启动失败 - Journalnode 日志中存在致命错误

  • 772

我的 Hadoop 集群有问题

Centos 7.3 Hortonworks Ambari 2.4.2 Hortonworks HDP 2.5.3

虽然日志节点成功启动，但它们有以下错误，也可以发现它是可疑的：

2017-04-05 17:15:05,653 ERROR RECEIVED SIGNAL 15: SIGTERM

这个错误的背景如下......

昨天我注意到其中一个数据节点失败并停止了。日志中有以下错误：

2017-04-05 15:50:11,168 ERROR datanode.DataNode (BPServiceActor.java:run(752)) - Initialization failed for Block pool <registering> (Datanode Uuid be2286f5-00d7-4758-b89a-45e2304cabe3) service to master02.mydomain.local/10.0.109.23:8020.

虽然看到音量错误，但我能够浏览 /grid/13/

所以我想在这个stackoverflow问题中尝试以下答案：

Datanode 无法正确启动

首先，我删除了 /grid/13/hadoop/hdfs (/grid/13/hadoop/hdfs/data) 下的数据文件夹并尝试启动 datanode。

它再次失败并出现同样的错误，所以我使用了 namenode 格式。我的集群是新的和空的，所以我对任何解决方案都很好，包括格式：

（在第一次尝试中，我给出了块池 ID 而不是 clusterId，命令失败。）

./hdfs namenode -format -clusterId <myClusterId>

在这种格式之后，其中一个名称节点失败了。当我尝试重新启动所有 HDFS 组件时，两个名称节点都失败了。

任何意见表示赞赏。

  1. Best Answer

    https://nicholasmaillard.wordpress.com/2015/07/20/formatting-hdfs/

    "Hdfs HA 格式化

    在 HA 中，事情变得有点复杂。在 HA 中，备用和活动名称节点具有由日志节点服务管理的共享存储。HA 依靠故障转移场景从 StandBy 切换到 Active Namenode，并且与 hadoop 中的任何其他系统一样，它使用 zookeeper。正如您所看到的，还有一些需要注意格式化操作。

    最初的步骤非常接近

    停止 Hdfs 服务 仅启动日志节点（因为它们需要知道格式） 在第一个 namenode 上（作为用户 hdfs） hadoop namenode -format​ hdfs namenode -initializeSharedEdits -force （对于日志节点） hdfs zkfc -formatZK -force（强制zookeeper重新初始化）​重新启动第一个namenode 在第二个namenode hdfs namenode -bootstrapStandby -force（强制与第一个namenode同步）在每个datanode上清除数据目录重新启动HDFS服务这是一个非常简单的格式化的分步指南。在以后的文章中，我们将介绍如何修复 HDFS 中的常见错误”
