【livy-8.0-2.12 spark3.2.1】kerberos认证问题

livy.conf
```
livy.server.launch.kerberos.keytab=xxx.keytab
livy.server.launch.kerberos.principal=xxx@HADOOP.COM
```
我确定keytab文件和principal是正确的，但是在创建interactive sesison时报错
```

```
若在spark-default.conf中增加
```
spark.kerberos.keytab=xxx.keytab
spark.kerberos.principal=xxx@HADOOP.COM
```
则以上问题解决，但是，livy server日志中一直在输出
```

```
请给我提供一些帮助，谢谢！

Start with the livy.conf settings and the Spark 3.2.1 session-creation logs, then compare them with the spark-default.conf Kerberos settings shown in the report. Trace the failed Hadoop connection to into1:8020 and determine why the Livy server still lacks a valid Kerberos TGT; done means interactive sessions work without recurring GSS warnings.
