Can't start after installation
log:
Caused by: java.sql.SQLException: Unable to open a test connection to the given database. JDBC url = jdbc:mysql://hadoop000:3306/metastore?createDatabaseIfNotExist=true, username = root. Terminating connection pool (set lazyInit to true if you expect to start your database after your app). Original Exception: ------
java.sql.SQLException: Access denied for user 'root'@'hadoop000' (using password: YES)
at com.mysql.jdbc.SQLError.createSQLException(SQLError.java:964)
After checking online, the solution is summarized
1. Check whether hive-site.xml is configured correctly, and the mysql account password cannot be wrongly written.
2. hive is not initialized, initialized
schematool -dbType mysql -initSchema
3. The hive version is too high.
4. The problem of derby-10.11.1.1.jar under HIVE_HOME/lib was solved successfully by replacing derby-10.11.1.1.jar with derby-10.10.2.0.jar
To sum up, my problem is that the mysql password in the hive-site.xml configuration file is wrong.
An essential item before configuring hive, grant permissions to mysql
mysql -uroot -p
>grant all privileges on *.* to root@"%" identified by "123456" with grant option; >grant all privileges on *.* to root@"hadoop000" identified by "123456" with grant option; >grant all privileges on *.* to root@"localhost" identified by "123456" with grant option;
>quit;
解释：
grant permission 1, permission 2, ... permission n on database name. table name to user name@user address identified by 'connection password';)
* By default, the mysql database only allows root users to log in through localhost/127.0.0.1
* In the statement above with grant:
all: indicates all permissions;
*.*: Represents database.data table;
root: Indicates which user is authorized, the user name can be arbitrarily specified, if not, it will be created automatically;
'hadoop000' : which host to authorize to
'123456': The password to authorize the user to log in
If you are not sure if you are successful, you can check mysql.user
mysql >select host,user,password from mysql.user;
