初始化hive的元数据库报：bash: schematool: 未找到命令

挨个检查

1.环境变量

vi /etc/profile.d/my_env.sh

export HIVE_HOME=/home/zheng/softwarre/hive

export HCATALOG_HOME=/home/zheng/software/hive/hcatalog

export PATH=$PATH:$HIVE_HOME/bin:$HCATALOG_HOME/bin:$HCATALOG_HOME/sbin

//注意是否刷新 source /etc/profile

2. hive.site.xml文件

 <property>
     <name>javax.jdo.option.ConnectionURL</name>
     <value>jdbc:mysql://192.168.30.128:3306/hive?useUnicode=true&amp;createDatabaseIfNotExist=true&amp;characterEncoding=UTF8&amp;useSSL=false&amp;serverTimeZone=GMT</value>
 </property>

 <!-- jdbc mysql驱动 -->
 <property>
     <name>javax.jdo.option.ConnectionDriverName</name>
     <value>com.mysql.cj.jdbc.Driver</value>
 </property>

 <!-- mysql的用户名和密码 -->
 <property>
     <name>javax.jdo.option.ConnectionUserName</name>
     <value>root</value>
 </property>
 <property>
     <name>javax.jdo.option.ConnectionPassword</name>
     <value>131127xx</value>
 </property>
 <!-- 日志目录 -->
 <property>
     <name>hive.querylog.location</name>
     <value>/home/zheng/software/hive/log</value>
 </property>

 <!-- 设置metastore的节点信息 -->
 <property>
     <name>hive.metastore.uris</name>
     <value>thrift://192.168.30.128:9083</value>
 </property>

<property> <name>hive.querylog.location</name> <value>/home/zheng/sofeware/hive/log</value> <description>Location of Hive run time structured log file</description> </property> <property> <name>hive.exec.local.scratchdir</name> <value>/home/zheng/software/hive/local</value> <description>Local scratch space for Hive jobs</description> </property> <property> <name>hive.downloaded.resources.dir</name> <value>/home/zheng/software/hive/resources</value> <description>Temporary local directory for added resources in the remote filesystem.</description> </property>

//注意路径问题

//hive-site.xml配置文件中，3215行有特殊字符“ &#8”，需要将此特殊符号删除掉

** 3.hive/lib目录下是否有mysql驱动包**

删除hive/lib目录下原有的 protobuf-java-2.5.0.jar 文件

将其换为: protobuf-java-3.5.1.jar

删除 hive/lib目录下原有 guava-19.0.jar

将其换位hadoop下的guava-27.0-jre.jar rm -r guava-19.0.jar

我因为环境变量拼写错误导致无法初始化hive
