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：

Connecting to jdbc:hive2://localhost:10000/default

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

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