分析错误可以看到，是因为执行sql脚本 hive-schema-1.2.1000.mysql.sql中的sql报语法错误。开始以为是因为sql脚本的版本跟我们所使用的mysql数据库的版本不匹配导致，结果将 hive-schema-1.2.1000.mysql.sql中/*!40101……这种开头的sql语句都删除了，重启hiveMetastore，依然报sql语法错误。此时便可排除mysql版本的原因。
继续看错误日志：
错误是执行/usr/hdp/current/hive-metastore/bin/schematool -initSchema -dbType mysql -userName hive -passWord [PROTECTED] -verbose这个指令时触发的，看了下下面打印的日志：
Metastore connection URL: jdbc:derby:;databaseName=metastore_db;create=true
Metastore Connection Driver : org.apache.derby.jdbc.EmbeddedDriver
Metastore connection User: hive
发现连接元数据库的databaseName用的居然不是我们传入的hive，而是metastore_db；
驱动Driver也不是mysql的驱动，而是本地derby数据库的驱动org.apache.derby.jdbc.EmbeddedDriver
说明虽然我们调用schematool 指令传入的数据类型是mysql，传入的数据库名也是mysql的，但实际调用却是derby数据库，所以才会因为在derby数据库上执行mysql的sql脚本文件而一直包sql语法错误。
第一想到的就是我们的配置文件hive-site.xml有问题，检查配置正确，关于metastore的配置均是mysql。
后来发现在/etc/haddoop/conf下还有一个hive-site.xml,果然，该配置文件没有任何关于matastroe的配置项，将/etc/hive/conf/hive-site.xml拷贝过来替换这个文件，解决问题
PS:derby数据库是默认的hiveMetaStore数据库类型，如果我们不指定使用mysql或者oracle等其他数据库，则默认使用derby数据库。
所以，可以分析出，初始化hiveMetaStore数据库时，拼接执行指令/usr/hdp/current/hive-metastore/bin/schematool -initSchema -dbType mysql -userName hive -passWord [PROTECTED] -verbose用的是/etc/hive/conf/hive-site.xml，但是提交到yarn中去执行指令的时候，会再次读取/etc/haddoop/conf/hive-site.xml中的配置项。
