How to Solve Azkaban startup error

Environment.
One virtual machine (web and exector both on one machine)
MySQL 8.x (most of the later problems are due to him)
Hive-3.1.2
Azkaban-exec-server-3.84.4
Azkaban-web-server-3.84.4
1. SLF4J problems:
ERROR [StdOutErrRedirect] [Azkaban] SLF4J: Class path contains multiple SLF4J bindings.

2021/09/30 10:02:31.820 +0800 ERROR [StdOutErrRedirect] [Azkaban] SLF4J: Class path contains multiple SLF4J bindings.
2021/09/30 10:02:31.820 +0800 ERROR [StdOutErrRedirect] [Azkaban] SLF4J: Found binding in [jar:file:/opt/module/azkaban/azkaban-exec/lib/slf4j-log4j12-1.7.21.jar!/org/slf4j/impl/StaticLoggerBinder.class]

2021/09/30 10:02:31.820 +0800 ERROR [StdOutErrRedirect] [Azkaban] SLF4J: See http://www.slf4j.org/codes.html#multiple_bindings for an explanation.
2021/09/30 10:02:31.823 +0800 ERROR [StdOutErrRedirect] [Azkaban] SLF4J: Actual binding is of type [org.slf4j.impl.Log4jLoggerFactory]

Cause: conflict with log4j package in hive
solution: delete Azkaban exec/lib/slf4j-log4j12-1.7.21.jar or add. Bak suffix
command:

cd /azkaban-exec/lib
mv slf4j-log4j12-1.7.21.jar slf4j-log4j12-1.7.21.jar.bak

2. DB connection problems(MySQL 8)
ERROR [MySQLDataSource] [Azkaban] Failed to find write-enabled DB connection.

2021/09/30 10:23:33.973 +0800 ERROR [MySQLDataSource] [Azkaban] Failed to find write-enabled DB connection. Wait 15 seconds and retry. No.Attempt = 1
java.sql.SQLException: Cannot create PoolableConnectionFactory (java.lang.ClassCastException: java.math.BigInteger cannot be cast to java.lang.Long)
        at org.apache.commons.dbcp2.BasicDataSource.createPoolableConnectionFactory(BasicDataSource.java:2294)

Reason: there is a problem with the MySQL driver package. The MySQL driver package provided by Azkaban cannot connect to MySQL 8. Just change to mysql-connector-java-5.1.47, and then a usessl error will be reported. This can be changed to MySQL. Database = Azkaban?Usessl = false in azkaban.properties. (both web and exector will report this error. Just modify it in turn)

(you can refer to this.) https://blog.csdn.net/liumu243/article/details/81288884 ）
this error can be ignored or run. The main problem here is that the exector is not activated

curl -G "localhsot:12321/executor?action=activate" && echo
//Appears to prove successful activation
{status:success}
