datagrip出现 java.net.ConnectException: Connection refused: connect.
出现这样的情况要看一下hadoop有没有启动
start-all.sh
nohup /export/server/apache-hive-3.1.2-bin/bin/hive --service hiveserver2 &
scp -r /export/server/apache-hive-3.1.2-bin/ node3:/export/server/
/export/server/apache-hive-3.1.2-bin/bin/hive
show databases;
