How Dose the HDFS Kerberos be embedded into fluid and alluxio？

[wujiuhsu]

We use Tensorflow in our machine learning with data in hdfs, Estimator reads data from HDFS using dataset. We want to use fluid to speed up our training. When we run the demo in https://fluid-cloudnative.github.io/zh/samples/hdfs_configuration.html#%E8%BF%90%E8%A1%8C%E7%A4%BA%E4%BE%8B, we have a question how to embed the HDFS Kerberos to fluid? This error occurs in hdfs-master-0.

I think basically it depends on two features:

1. alluxio runtime supports pvc attributes. I think it's similar with https://github.com/fluid-cloudnative/fluid/blob/master/docs/zh/samples/gcs_configuration.md

2. options and jvmOptions should be set by following https://docs.alluxio.io/ee/user/stable/en/operation/Security.html
