[GitHub] [iceberg] zhangdove opened a new issue #1150: Add Inspecting tables example by HDFS path in the Iceberg User docs

zhangdove opened a new issue #1150:
URL: https://github.com/apache/iceberg/issues/1150


   In the docs of Spark(http://iceberg.apache.org/spark/#inspecting-tables ).Should we add some sample code for how to inspect tables by HDFS path?
   
   For exmaple:
   ```
       val table = catalog.loadTable(tableIdentifier)
       table.location()
       import org.apache.iceberg.MetadataTableType
       // To show table history by HDFS path
       spark.read.format("iceberg").load(table.location() + "#" + MetadataTableType.HISTORY).show( truncate = false)
       // To show the valid snapshots for a table by HDFS path
       spark.read.format("iceberg").load(table.location() + "#" + MetadataTableType.SNAPSHOTS).show( truncate = false)
       // To show a table’s file manifests and each file’s metadata by HDFS path
       spark.read.format("iceberg").load(table.location() + "#" + MetadataTableType.MANIFESTS).show( truncate = false)
       // To show a table’s data files and each file’s metadata by HDFS path
       spark.read.format("iceberg").load(table.location() + "#" + MetadataTableType.ALL_DATA_FILES).show( truncate = false)
   ```

   Well, seems we only have `hive catalog` examples. Sure, I think it will be helpful for users if we provide the hadoop catalogs example. 
   If you'd like to prepare a pull request, then please go ahead. 
   Thanks.
