Hive：无法连接到Docker内部的SQL

我正在尝试使用hadoop和hive创建一个docker容器.这是我的Dockerfile

FROM ubuntu:latest

USER root
RUN apt-get update
#RUN apt-get -y install default-jre
RUN apt-get install -y python-pip python-dev build-essential
RUN apt-get install -y libmysqlclient-dev

    apt-get upgrade -y && 
    apt-get install -y git

ENV HADOOP_HOME /opt/hadoop
ENV JAVA_HOME /usr/lib/jvm/java-8-openjdk-amd64

# install packages
RUN 
  apt-get update && apt-get install -y 
  ssh 
  rsync 
  vim

# create ssh keys
RUN 
  ssh-keygen -t rsa -P '' -f ~/.ssh/id_rsa && 
  cat ~/.ssh/id_rsa.pub >> ~/.ssh/authorized_keys && 
  chmod 0600 ~/.ssh/authorized_keys

RUN DEBIAN_FRONTEND=noninteractive apt install -y mysql-client
RUN DEBIAN_FRONTEND=noninteractive apt install -y mysql-server
RUN chown -R mysql:mysql /var/lib/mysql /var/log/mysql

WORKDIR /opt

RUN wget --no-check-certificate https://www-us.apache.org/dist/hadoop/common/hadoop-2.8.5/hadoop-2.8.5.tar.gz
RUN tar -xzf hadoop-2.8.5.tar.gz
RUN mv hadoop-2.8.5 $HADOOP_HOME
RUN echo "export JAVA_HOME=$JAVA_HOME" >> $HADOOP_HOME/etc/hadoop/hadoop-env.sh
RUN echo "PATH=$PATH:$HADOOP_HOME/bin" >> ~/.bashrc
RUN rm hadoop-2.8.5.tar.gz

ARG HIVE_VERSION
# Set HIVE_VERSION from arg if provided at build,env if provided at run,or default
# https://docs.docker.com/engine/reference/builder/#using-arg-variables

ENV HIVE_VERSION=${HIVE_VERSION:-2.3.2}

ENV HIVE_HOME /opt/hive
ENV PATH $HIVE_HOME/bin:$PATH
RUN echo "PATH=$PATH:$HIVE_HOME/bin" >> ~/.bashrc

#Install Hive and PostgreSQL JDBC
RUN apt-get update && apt-get install -y wget procps &&

    rm apache-hive-$HIVE_VERSION-bin.tar.gz && 
    apt-get clean && 
    rm -rf /var/lib/apt/lists/*

ADD mysql-connector-java-5.1.47.jar /opt/hive/lib
ADD hive-site.xml /opt/hive/conf

这是hive-site.xml

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<?xml-stylesheet type="text/xsl" href="configuration.xsl"?>
<configuration>

<property>
  <name>javax.jdo.option.ConnectionURL</name>

</property>


<property>
  <name>javax.jdo.option.ConnectionDriverName</name>
  <value>com.mysql.jdbc.Driver</value>
</property>

<property>

  <value>root</value>
</property>

<property>
  <name>javax.jdo.option.ConnectionPassword</name>
  <value>password</value>

  <value>true</value>
</property>

<property>

 </property>

</configuration>

我能够构建和运行容器.当我执行到容器中时,我可以轻松地执行

root@c29fa91db6a2:/opt/hive/conf# mysql -uroot -ppassword
mysql: [Warning] Using a password on the command line interface can be insecure.

但是当我尝试做蜂巢-服务元存储时,我得到了

Caused by: java.sql.SQLException: Unable to open a test connection to the given database. JDBC url = jdbc:mysql://localhost:3306/metastore?createDatabaseIfNotExist=true&autoReconnect=true&useSSL=false,username = root. Terminating connection pool (set lazyInit to true if you expect to start your database after your app). Original Exception: ------
com.mysql.jdbc.exceptions.jdbc4.MySQLNonTransientConnectionException: Could not create connection to database server. Attempted reconnect 3 times. Giving up.

在堆栈跟踪的更深处,我看到了

Caused by: java.sql.SQLException: Access denied for user 'root'@'localhost'
    at com.mysql.jdbc.SQLError.createSQLException(SQLError.java:965) ~[mysql-connector-java-5.1.47.jar:5.1.47]

但是,这是root用户拥有的授予
