Install hive-2.1.0 for the first time, log in to the hive shell command line through bin/hive, and report the following error:

According to the log prompt, the metadata has not been initialized. You can initialize the source database through the ./schematool -initSchema -dbType command, because I am a mysql database here, and I know that I execute the following commands:

Log in to the hive shell through the bin/hive command again, and successfully log in, and the problem is solved. I have been using hive-0.13.1 before. You can log in directly without initializing the database when using hive for the first time.
