java - Hbase MasterNotRunningException 尽管 Hmaster、regionserver 和 Zookeeper 已启动

Question

我已经启动了 hbase，所有守护进程都在运行。

 $ jps
8482 HQuorumPeer
25105 RemoteMavenServer
9133 SecondaryNameNode
11883 HRegionServer
13793 Jps
8545 NameNode
8572 HMaster
11519 Main
25029 Main
8851 DataNode
9435 RunJar

现在让我们尝试列出表格:

hbase(main):004:0* list
        TABLE                                                                                                                                                   

ERROR: org.apache.hadoop.hbase.MasterNotRunningException: Retried 7 times

Here is some help for this command:
List all tables in hbase. Optional regular expression parameter could

但是，正如您怀疑的那样，hbase gui 未在 60030 上运行。我没有在 hbase 日志中看到错误来解释原因。

Answer 1

而且 HBase Web UI 没有运行，是吗？在单节点伪分布式集群完全崩溃后，我遇到了类似的事情。 HDFS 无法退出安全模式。

1. 使用 hadoop dfsadmin -safemode get 检查 HDFS 是否处于安全模式。
2. 如果是这样，手动强制安全模式退出 hadoop dfsadmin -safemode leave。
3. 您应该会看到进展 - 至少应该可以看到 HBase 网络用户界面。
4. 执行 HDFS fsck:hadoop fsck/-move。
5. 好的，如果一切正常，最好执行 hbase hbck 检查。

您可能需要的其他提示:

• 使用 netstat -n -a 检查区域服务器绑定(bind)的位置(检查端口在你的配置中)。碰巧绑定(bind)错了界面。也请搜索论坛 - Hadoop 有问题绑定(bind)和 IPv6 ( check this for example )。
• 使用 hadoop dfsadmin 检查 hadoop 是否真的退出了安全模式
-安全模式获取。 HBase 在完成之前不会完全启动。
