HBase shell Find ERROR: org.apache.hadoop.hbase.PleaseHoldException: Master is initializing

Problem description

Because of the HBase version, after I changed the HBase version, I opened the HBase shell query table and reported the following error:

How to solve it

The above problems are generally the cause of the failure of hregionserver node.

    1. first step, JPS checks whether its hregionserver node is normally opened (mostly hung up) and looks at the configuration file hbase-site.xml (my problem is here, because the installation has changed the version, and it has not been integrated with Phoneix yet, it is necessary to comment out all the Phoenix mapping configuration in the configuration file, otherwise hregionserver will not start normally)

 

    1. the following is a positive list Exact configuration file </ OL>

3. Close HBase, delete/HBase on HDFS and restart HBase

--Close hbase
stop-hbase.sh
--delete /hbase
hadoop fs -rm -r /hbase
--start hbase
start-hbase.sh

Note: in case of this kind of error, check whether the configuration file is correct, restart HBase (restart needs to delete/HBase), that is, follow step 3 to do it again.
