DBeaver访问不了kerberos环境的hive

1、错误：unsupported key type found the default TGT: 18

GSS initiate failed [Caused by GSSException: No valid credentials provided (Mechanism level: Failed to find any Kerberos tgt)]

* 原因：这个是AES256加密算法，需要安装JCE POLICY。

* 解决办法1：

   1）下面地址下载JCE包：

         http://www.oracle.com/technetwork/java/javase/downloads/jce8-download-2133166.html

   2）解压压缩包，local_policy.jar和US_export_policy.jar这两个jar包放到$JAVA_HOME/jre/lib/security/policy/limited目录。

* 解决办法2：

   1）修改kerberos client的加密方式：

[libdefaults]
 dns_lookup_realm = false
 ticket_lifetime = 24h
 renew_lifetime = 7d
 forwardable = true
 rdns = false
 default_realm = XXX.COM
 default_tgs_enctypes = aes256-cts aes128-cts arcfour-hmac-md5 des-cbc-md5 des-cbc-crc
 default_tkt_enctypes = arcfour-hmac-md5 aes256-cts aes128-cts des-cbc-md5 des-cbc-crc
 permitted_enctypes = aes256-cts aes128-cts arcfour-hmac-md5 des-cbc-md5 des-cbc-crc

   2）修改前：

       

   3）修改后：
