Hbase 错误“错误：KeeperErrorCode = NoNode for /hbase/master”

在 hbase shell 中执行任何命令时，我在 hbase shell 中收到以下错误“ERROR: KeeperErrorCode = NoNode for /hbase/master”。

启动HBASE：

    HOSTCHND:hbase-2.0.0 gvm$ ./bin/start-hbase.sh
    localhost: running zookeeper, logging to /usr/local/Cellar/hbase-2.0.0/bin/../logs/hbase-gvm-zookeeper-HOSTCHND.local.out
    running master, logging to /usr/local/Cellar/hbase-2.0.0/logs/hbase-gvm-master-HOSTCHND.local.out
    : running regionserver, logging to /usr/local/Cellar/hbase-2.0.0/logs/hbase-gvm-regionserver-HOSTCHND.local.out

在 HBASE SHELL 中检查状态时：

    hbase(main):001:0> status

    ERROR: KeeperErrorCode = NoNode for /hbase/master

    Show cluster status. Can be 'summary', 'simple', 'detailed', or 'replication'. The
    default is 'summary'. Examples:

    hbase> status
    hbase> status 'simple'
    hbase> status 'summary'
    hbase> status 'detailed'
    hbase> status 'replication'
    hbase> status 'replication', 'source'
    hbase> status 'replication', 'sink'

   hbase(main):002:0> 

hbase-site.xml

请告诉我为什么执行 hbase 命令时会出现此错误？

就我而言，我收到了这个“ERROR: KeeperErrorCode = NoNode for /hbase/master“ 因为HMaster进程没有运行。

检查与jps命令。

hdusr@hdp-master-1:$ jps
27504 Main
32755 DataNode
23316 HQuorumPeer
27957 Jps
646 SecondaryNameNode
27097 HMaster
23609 HRegionServer
1562 Master
1722 Worker
911 ResourceManager
32559 NameNode
1167 NodeManager

如果你没有看到HMaster进程如上面的列表所示，这就是原因ERROR: KeeperErrorCode = NoNode.在 hbase shell 中。

In $HBASE_HOME/logs目录检查hbase-***-master.log对于特定的错误。

就我而言，有两个原因，

First :

WARN  [main-SendThread(localhost:2181)] zookeeper.ClientCnxn: Session 0x0 for server null, unexpected error, closing socket connection and attempting reconnect
java.net.ConnectException: Connection timed out

我通过在 hbase-site.xml 中将“localhost”替换为“我的机器的主机名”来解决这个问题。由此answer

Second :

    ERROR [master/spark-hdp-master-1:16000:becomeActiveMaster] master.HMaster: Failed to become active masterorg.apache.hadoop.ipc.RemoteException(org.apache.hadoop.security.AccessControlException): org.apache.hadoop.security.AccessControlException: SIMPLE authentication is not enabled.  Available:[TOKEN]

这是因为hbase-site.xml中的hdfs端口与hadoop的core-site.xml中的不同。
