Unable to initiate metastore in Hive with Hodoop

I have Hadoop 3.3.2, Hive 3.1.3, MySql 8.0.29(apt install mysql-server) installed. MySql is running properly with mysql -h 127.0.0.1 -u debian-sys-maint -p command. But unable to run any command in Hive. I'm getting FAILED: HiveException java.lang.RuntimeException: Unable to instantiate org.apache.hadoop.hive.ql.metadata.SessionHiveMetaStoreClient exception.
Then in SO, I found this question on SO, which says to execute hive --service metastore. But, when I execute this command, I get this error:
2022-07-24 17:15:57: Starting Hive Metastore Server

I also have mysql-connector-java-5.1.9.jar in $HIVE_HOME/lib. I am not getting what I am missing. Any help would be appreciated.

Thanks to suggestions by #ggordon in comments under the question. I followed the steps in this website with some small modifications.
When I executed mysql -u debian-sys-maint -p, I was getting ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (13) error. So, I changed it to use loopback address: mysql -h 127.0.0.1 -u debian-sys-maint -p.
CREATE USER 'hiveuser'#'%' IDENTIFIED BY 'hivepassword' has to be changed to CREATE USER 'hiveuser'#'127.0.0.1' IDENTIFIED BY 'hivepassword', since that is what we are using. (I missed this step in question)
GRANT all on . to hiveuser was not working for me. So, after some googling, I changed it to GRANT all on hive_metastore.* to 'hiveuser'#'127.0.0.1'.
javax.jdo.option.ConnectionURL property in $HIVE_HOME/conf/hive-site.xml was set to jdbc:mysql://localhost/hive_metastore?createDatabaseIfNotExist=true. It has to be changed to jdbc:mysql://127.0.0.1/hive_metastore?createDatabaseIfNotExist=true.
With these changes, I followed steps in the above linked site, and it is working fine now.

Configuring Single Sign-on with OpenID Connect

Following steps as described here:
I think I have configured steps 1-4 but starting up my IS V5.7 for step 5 falls apart.
Initial problems like an incorrectly formatted user-mgt.xml and missing jdbc jar file I was able to solve but I don't have a clue how the remaining problems are to be addressed.
Configuration complexity is huge in this environment.
I run Windows 10, Java 1.8 IS 5.7 and Apim 2.6 & MySQL 5.7
Don't seem to be able to attach files.
At the end of this post I will list the server log starting from where things go wrong.
if in need for further info please let me know
Anyone any suggestions?
Thanks Peter

Caused by: com.mysql.cj.exceptions.CJCommunicationsException: Communications link failure
The last packet sent successfully to the server was 0 milliseconds ago. The driver has not received any packets from the server.
As per the above stack trace, DB connection has failed.
DB connection can be failed due to one or more of the following causes:
1.IP address or hostname in JDBC URL is wrong.
2. Hostname in JDBC URL is not recognized by local DNS server.
3. Port number is missing or wrong in JDBC URL.
4. DB server is down.
5. DB server doesn't accept TCP/IP connections.
6. DB server has run out of connections.
7. Something in between Java and DB is blocking connections, e.g. a firewall or proxy.
8. An issue with Jdbc driver like incompatible version or wrongly-placed it
9. Miss some parameters in JDBC connection Url like useSSL
Our Recommendations
To resolve any of the above mentioned issues, you can follow below given instructions.
Verify and test them with ping.
Refresh DNS or use IP address in JDBC URL instead.
Verify it based on my.cnf of MySQL DB.
Start the DB.
Verify if mysqld is started without the --skip-networking option.
Disable firewall and/or configure firewall/proxy to allow/forward the port.
Putting correct Jdbc driver to correct place
Pass the required parametres to establish the connection

UcanAccess error reading .MDB db from samba connection

I'm using UcanAccess (http://ucanaccess.sourceforge.net/site.html) to read a .MDB database from Java.
The application is running in a Ubuntu server and it is reading the database from a Samba connection.
On Windows machine it works, but on Linux I've some problems.
Here some data:
Url: jdbc:ucanaccess:///mnt/database/TEST.MDB;jackcessOpener=it.plugins.CryptCodecOpener
The database requires a password when I open it from Access. The database is used from another application, in fact I see in the same folder the .ldb file.
When I try to read data from DB I've this exception:

But if I do a cp originalDatabase.MDB copiedDatabase.MDB and I change UcanAccess url using the copied database, everything works fine without any change!
This is how I mounted the share:
//192.168.101.100/g/DATABASE /mnt/database cifs user=,password=,gid=1005,uid=1001 0 0
where 1001 is the uid of the user that runs my java application.
I want to point out that the same application on Windows works fine without the need to copy the original database in order to access to it.
Am I missing something?

I know for sure there's nothing wrong with the credential and AuthMech. Someone please help.

Problem solved. I upgraded my Impala JDBC driver to 41, and got rid of transportMode=http;httpPath=cliservice in my connection string.

ERROR: com.***.CalculateScore - org.springframework.dao.DataAccessResourceFailureException: Cannot open connection; nested exception is org.hibernate.exception.JDBCConnectionException: Cannot open connection
My program is using Hibernate with MySQL in Java over JDBC.
The operation system is Ubuntu 12.04. A reinstallation of the system did't fix the problem.
Do someone have an idea what's going wrong?

This is due to NoRouteToHostException. That case for the network configuration state.
Signals that an error occurred while attempting to connect a socket to a remote address and port. Typically, the remote host cannot be reached because of an intervening firewall, or if an intermediate router is down.
Check How to avoid a NoRouteToHostException.
