Fri May 18 09:51:14 CST 2018 WARN: Establishing SSL connection without server's identity verification is not recommended.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.

<description>
Enforce metastore schema version consistency.
True: Verify that version information stored in metastore matches with one from Hive jars. Also disable automatic schema migration attempt. Users are required to manully migrate schema after Hive upgrade which ensures proper metastore schema migration. (Default)
False: Warn if the version information stored in metastore doesn't match with one from in Hive jars.

问题的根本缘由是用户权限问题。apache
将hive.downloaded.resources.dir修改成绝对路径：session
<property>
<name>hive.downloaded.resources.dir</name>
<value>/home/hadoop/hive-2.2.0/tmp/${hive.session.id}_resources</value>
<description>Temporary local directory for added resources in the remote file system.</description>
</property>
若是还有问题，查看登陆用户是否有修改该目录文件的权限app

方法1：首先查看Metastore connection URL、Metastore Connection Driver和Metastore connection User三个选项的内容与hive-site.xml信息里面的内容同样，若是不正确请修改。ide
方法2：删除$HIVE_HOME/conf目录里面的metastore_db，并删除svg
而后从新格式化

错误分析：
从The root scratch dir: /home/hadoop/hive-2.2.0/hive on HDFS should be writable. Current permissions are: rwxr-xr-x能够看出。系统要求在hdfs上用户应该具有写权限，而从报错能够看出只有全部者具备写权限，全部组合其余用户不具有。
使用hadoop fs hadoop fs -chmod -R dir修改目录权限，以下
[root@hadoop-master bin]# hadoop fs -chmod 777 /home/hadoop/hive-2.2.0/hive
