hadoop - 如何修复 'NoNode for/hbase/master'

Question

我已经完成了具有3个节点(hadoop-master，hadoop-data1，hadoop-data2)的集群Hadoop。这似乎可行，但是当我尝试在其上安装hbase时，在hbase shell上执行此操作时仍然出现错误

status

这是hbase-site.xml配置:

<configuration>
  <property>
    <name>hbase.rootdir</name>
    <value>hdfs://hadoop-master:9000/hbase</value>
  </property>
  <property>
    <name>hbase.cluster.distributed</name>
    <value>true</value>
  </property>
  <property>
    <name>hbase.zookeeper.property.dataDir</name>
    <value>/usr/local/zookeeper</value>
  </property>
  <property>
    <name>hbase.zookeeper.quorum</name>
    <value>hadoop-master</value>
  </property>
  <property>
    <name>hbase.zookeeper.property.clientPort</name>
    <value>2181</value>
  </property>
</configuration>

并且群集似乎可以正常工作，因为我可以访问
http://IP_OF_MY_MASTER_NODE:8088/cluster/nodes
这是我用jps得到的

hadoop@hadoop-master:~$ jps
29713 ResourceManager
29029 NameNode
29893 NodeManager
29480 SecondaryNameNode
30568 HQuorumPeer
29213 DataNode
31101 Jps

hadoop@hadoop-data1:~$ jps
29348 Jps
28665 DataNode
28842 NodeManager

这是我的实际结果:

hadoop@hadoop-master:~$ /home/hadoop/hbase/hbase-2.1.4/bin/hbase shell

ERROR: KeeperErrorCode = NoNode for /hbase/master

在此先感谢您的帮助

由于 HMaster进程未运行，因此出现此错误。 checkin jps 。

在$HBASE_HOME/logs目录中，检查hbase-***-master.log是否存在特定错误。

还要检查this answer。
