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:
[hadoop@db03 hive-2.1.0]$ bin/schematool -initSchema -dbType mysql which: no hbase in (/opt/service/jdk1.7.0_67/bin:/opt/service/jdk1.7.0_67/jre/bin:/opt/mysql-5.6.24/bin:/opt/service/jdk1.7.0_67/bin:/opt/service/jdk1.7.0_67/jre/bin:/usr/lib64/qt-3.3/bin:/usr/local/bin:/bin:/usr/bin:/usr/local/sbin:/usr/sbin:/sbin:/home/hadoop/bin) SLF4J: Class path contains multiple SLF4J bindings.

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.
