Failed to start role of YARN Queue Manager

Question

I encountered an error with the following description after installing YARN Queue Manager:

Caused by: org.h2.jdbc.JdbcSQLNonTransientException: Log file error: "/var/lib/hadoop-yarn/config-service.trace.db", cause: "java.io.FileNotFoundException: /var/lib/hadoop-yarn/config-service.trace.db (Permission denied)" [90034-198] at org.h2.message.DbException.getJdbcSQLException(DbException.java:502) at org.h2.message.DbException.getJdbcSQLException(DbException.java:427) ... 38 more Caused by: java.io.FileNotFoundException: /var/lib/hadoop-yarn/config-service.trace.db (Permission denied)

I have searched, but I couldn't find anyone experiencing the same error as me. Could you please assist me?😥
