Failed to drop database

I succeeded in creating the database in impala shell, but I failed to execute the drop database command, the error was as follows:

Query: drop database impala
ERROR: ImpalaRuntimeException: Error making 'dropDatabase' RPC to Hive Metastore:
CAUSED BY: MetaException: java.lang.RuntimeException: com.zaxxer.hikari.pool.HikariPool$PoolInitializationException: Failed to initialize pool: FATAL: password authentication failed for user "impala"
CAUSED BY: RuntimeException: com.zaxxer.hikari.pool.HikariPool$PoolInitializationException: Failed to initialize pool: FATAL: password authentication failed for user "impala"
CAUSED BY: PoolInitializationException: Failed to initialize pool: FATAL: password authentication failed for user "impala"
CAUSED BY: PSQLException: FATAL: password authentication failed for user "impala"

After I execute invalidate metadata, I can't see the database that failed to be deleted.
