> {{org.apache.hadoop.fs.azure.NativeAzureFileSystem}} does not override {{FileSystem#getHomeDirectory()}}
method.
> So, whenever {{NativeAzureFileSystem#getHomeDirectory()}} gets called {{getHomeDirectory()}}
from {{FileSystem}} will be invoked, which has code like below,
> {code}
> public Path getHomeDirectory() {
>     return this.makeQualified(
>         new Path(USER_HOME_PREFIX + "/" + System.getProperty("user.name")));
>   }
> {code}
> In secure environment, it returns home directory of {{System.getProperty("user.name")}}
instead of Kerberos principal/UGI.
> So, the proposal is to override the {{getHomeDirectory()}} method in {{NativeAzureFileSystem}}
and have it return the home directory for the Kerberos principal/ugi.
