Error when run gravitino-fileset-example.ipynb

[shaofengshi]

Start the playground docker images, and then open Jupyter, run the gravitino-fileset-example.ipynb.

In the second step, I got this error:

from hdfs import InsecureClient

# Create a HDFS connector client
hdfs_client = InsecureClient('http://hive:50070', user='root')

# List HDFS file and directories
print(hdfs_client.list('/user/datastrato'))

HdfsError: File /user/datastrato does not exist.

Then I look into the HDFS, there is no "/user/datastrato" folder; Under "/user" there is only "/user/hive"
