Error ERROR: KeeperErrorCode = NoNode for /hbase/master
Cause Analysis
Modifying the hbase configuration file hbase-site.xml in a pseudo-distributed environment will result in incomplete files. The files on hadoop are inconsistent with the local files, so when entering hbase, the list cannot search for the entire previous file. In short, before the distributed storage, there were 3 machines, 1 of which stored 1 block to form a complete file. Now that 2 are removed, an error will be reported when querying again.
solution
1. Exit the hbase shell
hbase:002:0> exit
2. Exit hbase
[root@node1 hbase-2.4.13]# stop-hbase.sh
3. Exit hadoop
[root@node1 hbase-2.4.13]# stop-all.sh
4. View progress
[root@node1 hbase-2.4.13]# jps
5. Restart hadoop
[root@node1 hbase-2.4.13]# start-all.sh
6. Enter the hadoop file path
[root@node1 hbase-2.4.13]# cd /usr/local/hadoop-3.3.0
7. View hadoop root directory
[root@node1 hadoop-3.3.0]# hadoop fs -ls /
8. Disable Hadoop Safe Mode
[root@node1 hadoop-3.3.0]# hdfs dfsadmin -safemode leave
9. delete hbase
[root@node1 hadoop-3.3.0]# hadoop fs -rm -r /hbase
10. View the directory again
[root@node1 hadoop-3.3.0]# hadoop fs -ls
11. Start hbase
[root@node1 hadoop-3.3.0]# start-hbase.sh
12. Enter the shell command line
[root@node1 hadoop-3.3.0]# hbase shell
13. View table
hbase:001:0> list
