    Description

      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,

      public Path getHomeDirectory() {
          return this.makeQualified(
              new Path(USER_HOME_PREFIX + "/" + System.getProperty("user.name")));
        }
      

      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.
