在 UserGroupInformation.loginUserFromKeytab(principal, keytabLocation) 处报错：

java.io.IOException: Login failure for hbase@XXXX.COM from keytab F:/hbase/hbase.keytab: javax.security.auth.login.LoginException: no supported default etypes for default_tkt_enctypes

参数分别为 hbase@XXXX.COM，F:/hbase/hbase.keytab 。

java.security.krb5.conf设置为F:/hbase/krb5.conf :

处理：下载jdk8对应的JCE文件添加到jdk/jre/lib/security下

初步推测是，jdk需要相应的加密解密方式来处理hbase.keytab 文件。
