HIVE2 ：beeline连接设置用户名和密码注意问题

beeline connect有几种方式，见Hive-site.xml,缺省为NONE。

 <property>
    <name>hive.server2.authentication</name>
    <value>NONE</value>
    <description>
      Expects one of [nosasl, none, ldap, kerberos, pam, custom].
      Client authentication types.
        NONE: no authentication check
        LDAP: LDAP/AD based authentication
        KERBEROS: Kerberos/GSSAPI authentication
        CUSTOM: Custom authentication provider
                (Use with property hive.server2.custom.authentication.class)
        PAM: Pluggable authentication module
        NOSASL:  Raw transport
    </description>
  </property>

设置相应用户名和密码

<property>
    <name>hive.server2.thrift.client.user</name>
    <value>root</value>
    <description>Username to use against thrift client</description>
  </property>
  <property>
    <name>hive.server2.thrift.client.password</name>
    <value>123456</value>
    <description>Password to use against thrift client</description>

  </property>

注意这里设置的用户要求对inode="/tmp/hive" 有执行权限，否则会出现下列问题：

Enter username for jdbc:hive2://localhost:10000/default: hive
Enter password for jdbc:hive2://localhost:10000/default: **
