启动Hive时出现：
Exception in thread "main" java.lang.RuntimeException: java.lang.IllegalArgumentException: java.net.URISyntaxException: Relative path in absolute URI: ${system:java.io.tmpdir%7D/$%7Bsystem:user.name%7D
解决方法：
在 hive-site.xml 中替换 system:java.io.tmpdir 为某一个文件夹即可
初始化Hive时出现：
[root@had lib]# schematool -dbType mysql -initSchema
Metastore connection URL: jdbc:derby:;databaseName=metastore_db;create=true
Metastore Connection Driver : org.apache.derby.jdbc.EmbeddedDriver

原因：在Hadoop和Hive中的 jline-2.12.jar 包冲突。
Hadoop:
/opt/hadoop/share/hadoop/yarn/lib
Hive:
/opt/hive/lib
配置本地模式启动hive时：
[root@had conf]# hive
Logging initialized using configuration in jar:file:/opt/hive/lib/hive-common-1.2.2.jar!/hive-log4j.properties

According to MySQL 5.5.45+, 5.6.26+ and 5.7.6+ requirements SSL connection must be established by default if explicit option isn't set. For compliance with existing applications not using SSL the verifyServerCertificate property is set to 'false'. You need either to explicitly disable SSL by setting useSSL=false, or set useSSL=true and provide truststore for server certificate verification.
