Hbase MasterNotRunningException，盡管Hmaster，regionserver和Zookeeper已啟動

Question

我已經啟動了hbase並且所有守護程序都在運行。

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

現在讓我們嘗試列出表：

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
be used to filter the output. Examples:

但是，您懷疑hbase gui不在60030上運行。我看不到hbase日志中的錯誤來解釋原因。

Answer 1

而且HBase Web UI沒有運行，是嗎？ 單節點偽分布式集群完全崩潰后，我也遇到了類似的情況。 HDFS無法退出安全模式。

1. 使用hadoop dfsadmin -safemode get檢查HDFS是否不在安全模式下。
2. 如果是這樣，請手動強制安全模式退出hadoop dfsadmin -safemode leave 。
3. 您應該看到進度-至少HBase Web UI應該可見。
4. 執行HDFS fsck： hadoop fsck / -move 。
5. 好的，如果一切順利，最好執行hbase hbck檢查。

您可能需要的其他提示：

• 檢查區域服務器與netstat -n -a綁定的位置（檢查配置中的端口）。 碰巧它綁定在錯誤的接口上。 還請搜索論壇-Hadoop綁定和IPv6存在問題（ 例如，請檢查此問題 ）。
• 使用hadoop dfsadmin -safemode get檢查hadoop是否確實退出了安全模式。 HBase直到完成后才能完全啟動。
