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.
