hive

Cannot initialize metastore due to autoCreate error
javax.jdo.JDODataStoreException: Required table missing : "DBS" in Catalog "" Schema "". DataNucleus requires this table to perform its persistence operatio
ns. Either your MetaData is incorrect, or you need to enable "datanucleus.schema.autoCreateTables"

太复杂了，搞了一下午，直接使用schematool初始化

cd /hive-2.3.7/bin
./schematool -initSchema -dbType mysql

附上hive.site.xml
