This article mainly introduces "how to solve the inconsistency between old and new data in zookeeper". In daily operation, I believe that many people have doubts about how to solve the problem of inconsistency between new and old data in zookeeper.

I hope it will be helpful to answer the doubt of "how to solve the inconsistency between new and old data in zookeeper". Next, please follow the editor to study!
Data inconsistencies between new and old versions can lead to the following problems:
1. Both start-hbase.sh,HMaster and HRegionserver processes can be started, while stop-hbase.sh can only shut down the HMaster process, that is, HBase cannot shut down normally
two。 After starting HBase, execute hbase shell to enter hbase, and all kinds of commands cannot be executed normally, such as list, creating table and so on. This kind of error is generally reported: can't get master address from zookeeper; znode data=null
Solution:
1. Start the hadoop process first, start-all.sh
two。 Start the zookeeper process and zkServer.sh start respectively
3. Start the hbase process, start-hbase.sh
4. There is a zkCli.sh in the bin directory of zookeeper, run into
5. Run rmr / hbase after entering, and then quit exit
6. At this point, hbase can work properly.
