Unknown version specified for initialization: 3.1.0 schemaTool failed

yeah finally I have solved it no need of Cygwin.

first download these cmds and paste them in bin folder which you might have already done

https://github.com/HadiFadl/Hive-cmd

no need to repeat it if you have already done it :)

i have created the database in mysql by create database metastore_db;

my hive_site.xml looks like this because i choosed to use mysql, write your mysql username,password in place of root root.

<?xml version="1.0"?><?xml-stylesheet type="text/xsl" href="configuration.xsl"?><configuration>    <property>        <name>javax.jdo.option.ConnectionURL</name>        <value>jdbc:mysql://localhost:3307/metastore_db?createDatabaseIfNotExist=false&useSSL=true</value>        <description>metadata is stored in a MySQL server</description>    </property>    <property>        <name>javax.jdo.option.ConnectionDriverName</name>        <value>com.mysql.jdbc.Driver</value>        <description>MySQL JDBC driver class</description>    </property>    <property>        <name>javax.jdo.option.ConnectionUserName</name>        <value>root</value>        <description>user name for connecting to mysql server</description>    </property>    <property>        <name>javax.jdo.option.ConnectionPassword</name>        <value>root</value>        <description>password for connecting to mysql server</description>    </property></configuration>

write this in cmd:

hive --service schematool -dbType derby -initSchema

or write this if you are using mysql as backend:

hive --service schematool -dbType mysql -initSchema

if you get output at the end like

Initialization script completedschemaTool completed

you have successfully done it. else try to go to C:\apache-hive-3.1.2-bin\bin via cmd and then execute it.
